Abstract
Anionic, metal‐centered nucleophiles are emerging compounds with unique reactivities. Here, we describe the isolation and full characterization of the first tetraamido tin(II) dianion, its behavior as ligand towards transition metals, and its reactivity as a tin‐centered nucleophile. Experimental values such as the Tolman electronic parameter (TEP) and computations attest tin‐located σ‐donor ability exceeding that of carbenes or electron‐rich phosphines. Against transition metals, the stannate(II) can act as η1‐ or η5‐type ligand. With aldehydes, it reacts by hydride substitution to give valuable acyl stannates. The reductive dehalogenation of iodobenzene indicates facile redox pathways mediated by halogen bond interaction. Calix[4]pyrrolato stannate(II) represents the first example of this macrocyclic ligand in low‐valent p‐block element chemistry.

Abstract
A stable lithium stannenolate 7 was synthesized and isolated by the reaction of acylstannane 6 with LDA or tBu2MeSiLi in THF. 7 was characterized by X-ray crystallography and by NMR and UV-Vis spectroscopy. Spectroscopic and structural features, in combination with DFT quantum-mechanical calculations, indicate that 7 is best described as an acyl-substituted stannyl anion, adopting the stannenolate keto tautomeric structure.

Abstract
![]()
The formation of
a stable triacylgermenolate 2 as
a decisive intermediate was achieved by using three pathways. The
first two methods involve the reaction of KOtBu or
alternatively potassium with tetraacylgermane 1 yielding 2 via one electron transfer. The mechanism involves the formation
of radical anions (shown by EPR). This reaction is highly efficient
and selective. The third method is a classical salt metathesis reaction
toward 2 in nearly quantitative yield. The formation
of 2 was confirmed by NMR spectroscopy, UV–vis
measurements, and X-ray crystallography. Germenolate 2 serves as a starting point for a wide variety of organo-germanium
compounds. We demonstrate the potential of this intermediate by introducing
new types of Ge-based photoinitiators 4b–4f. The UV–vis absorption spectra of 4b–4f show considerably increased band intensities
due to the presence of eight or more chromophores. Moreover, compounds 4d–4f show absorption tailing up to 525
nm. The performance of these photoinitiators is demonstrated by spectroscopy
(time-resolved EPR, laser flash photolysis (LFP), photobleaching (UV–vis))
and photopolymerization experiments (photo-DSC measurements). Triacylgermenolate 2 was
obtained by using
KOtBu or alternatively potassium. The mechanism involves
the formation of radical anions (shown by EPR). The one-pot synthetic
protocol produces 2 in >95% yield, as confirmed by
NMR
spectroscopy and X-ray crystallography. Germenolate 2 serves as a starting point for a wide variety of organo-germanium
compounds. This was demonstrated by introducing new types of Ge-based
photoinitiators 4b−4f. Their performance
was analyzed by sophisticated spectroscopic methods and photopolymerization
experiments.

Abstract
The design of photoinitiating systems with excellent photochemical reactivities at 405nm LED is one of the obstacles to efficiently promote free radical polymerization in mild conditions (e.g., low light intensity, under air). Here, our actual search for new multicomponent photoinitiating systems at 405nm LED prompts us to develop new dyes based on push–pull structures. In the present paper, we chose two series of new dyes which possess indane-1,3-dione and 1H-cyclopenta naphthalene-1,3-dione groups as the electron-withdrawing groups, since they have the great potential to behave as sensitive and remarkable photoinitiators in vat photopolymerization/3D printing. When incorporated with a tertiary amine (ethyl dimethylaminobenzoate EDB, used as electron/hydrogen donor) and an iodonium salt (used as electron acceptor) as the three-component photoinitiating systems (PISs), and among a series of 21 dyes, 10 of them could efficiently promote the free radical photopolymerization of acrylates. Interestingly, steady state photolysis experiments revealed different behaviors of the dyes. Fluorescence experiments and free energy change calculations for redox processes were also carried out to investigate the relevant chemical mechanisms. Additionally, the formation of radicals from the investigated PISs was clearly observed by electron spin resonance (ESR) spin-trapping experiments. Finally, stereoscopic 3D patterns were successfully fabricated by the laser writing technique. In this work, the use of push–pull dyes based on the naphthalene scaffold as photoinitiators of polymerization is reported for the first time in a systematic study aiming at investigating the structure–performance relationship for irradiation carried out at 405 nm. By carefully selecting the electron donors used in the two series of push–pull dyes, novel and high-performance photoinitiating systems operating at 405 nm are thus proposed.

Abstract
Recently heavier Group 14 enolates showed their importance and applicability in a broad range of chemical transformations. They were found to be key intermediates during the synthesis of photoinitiators, as well as during the formation of complex silicon frameworks. This Minireview presents general strategies towards the synthesis of heavier Group 14 enolates (HG 14 enolates). Structural properties, as well as their spectroscopic behavior are outlined. This study may aid future development in this research area.

Abstract
Photopolymerization processes, and especially those carried out under visible light, are more and more widespread for their multiple advantages compared to thermal processes. In the present paper, new 1,8-naphthalimide derivatives are proposed as photoinitiators for free-radical polymerization upon visible light exposure using light-emitting diodes (LEDs) at 395, 405, and 470 nm. These photoinitiators are used in combination with both iodonium salts and phosphine. The synthesis of these compounds as well as their excellent polymerization initiation ability for methacrylate monomers are presented in this article. A full picture of the involved chemical mechanisms is also provided thanks to photolysis, radical characterization, and redox measurements.

Tetraacylstannanes as Long-Wavelength Visible-Light Photoinitiators with Intriguing Low Toxicity. Chemistry 2018; 24:8281-8285. [PMID: 29709089 PMCID: PMC6032833 DOI: 10.1002/chem.201801622] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Revised: 04/29/2018] [Indexed: 11/24/2022]
Abstract
The first tetraacylstannanes Sn[(CO)R]4 (R=2,4,6‐trimethylphenyl (1 a) and 2,6‐dimethylphenyl (1 b)), a class of highly efficient Sn‐based photoinitiators, were synthesized. The formation of these derivatives was confirmed by NMR spectroscopy, mass spectrometry, and X‐ray crystallography. The UV/Vis absorption spectra of 1 a, b reveal a significant redshift of the longest wavelength absorption compared to the corresponding germanium compounds. In contrast to the known toxicity of organotin derivatives, the AMES test and cytotoxicity studies reveal intriguing low toxicity. The excellent performance of 1 as photoinitiators is demonstrated by photobleaching (UV/Vis) and NMR/CIDNP investigations, as well as photo‐DSC studies.
