Abstract
Ir-catalysed borylation of phthalonitrile produces both 4-(Bpin)phthalonitrile (1) and 3,5-bis(Bpin)phthalonitrile (2), which are potential divergent intermediates for the synthesis of functionalized phthalocyanines. To exemplify the utility of 2, we have prepared a series of 3,5-bis-arylphthalonitriles that in turn undergo sterically controlled regioselective cyclotetramization to give previously unknown C4h 1,3,8,10,15,17,22,24-octaarylphthalocyanines.

Molecules 2019; 24:molecules24193610. [PMID: 31591340 PMCID: PMC6803875 DOI: 10.3390/molecules24193610] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2019] [Revised: 09/26/2019] [Accepted: 10/03/2019] [Indexed: 11/16/2022] Open
Abstract
The activation of halogen bonding by the substitution of the pentafluoro-λ6-sulfanyl (SF5) group was studied using a series of SF5-substituted iodobenzenes. The simulated electrostatic potential values of SF5-substituted iodobenzenes, the ab initio molecular orbital calculations of intermolecular interactions of SF5-substituted iodobenzenes with pyridine, and the 13C-NMR titration experiments of SF5-substituted iodobenzenes in the presence of pyridine or tetra (n-butyl) ammonium chloride (TBAC) indicated the obvious activation of halogen bonding, although this was highly dependent on the position of SF5-substitution on the benzene ring. It was found that 3,5-bis-SF5-iodobenzene was the most effective halogen bond donor, followed by o-SF5-substituted iodobenzene, while the m- and p-SF5 substitutions did not activate the halogen bonding of iodobenzenes. The similar ortho-effect was also confirmed by studies using a series of nitro (NO2)-substituted iodobenzenes. These observations are in good agreement with the corresponding Mulliken charge of iodine. The 2:1 halogen bonding complex of 3,5-bis-SF5-iodobenzene and 1,4-diazabicyclo[2.2.2]octane (DABCO) was also confirmed. Since SF5-containing compounds have emerged as promising novel pharmaceutical and agrochemical candidates, the 3,5-bis-SF5-iodobenzene unit may be an attractive fragment of rational drug design capable of halogen bonding with biomolecules.

Abstract
The trans-tetrafluoro-λ6-sulfane (SF4) group has been utilized as a unique three-dimensional building block for the linear connection of two independent N-heterocycles, pyridines and triazoles. The linearly connected heterocyclic compounds were synthesized by thermal Huisgen 1,3-dipolar cycloaddition between previously unknown pyridine SF4-alkynes and readily available azides, providing a series of rod-like SF4-connected N-heterocycles in good to excellent yields. X-ray crystallographic analysis of the target products revealed the trans-geometry of the SF4 group, which linearly connects two independent N-heterocycles. This research will open the field of chemistry of SF4-connected heterocyclic compounds.

Abstract
We have synthesized two novel phthalocyanines, (m-SF[Formula: see text]PhO)[Formula: see text]PcCu (7b) and (p-SF[Formula: see text]PhO)[Formula: see text]PcCu (7c), in order to investigate their flying-seed-like mesomorphism. Their phase transition behavior and the mesophase structure have been established by using a polarizing optical microscope, a differential scanning calorimeter, and a temperature-dependent small angle X-ray diffractometer. Very interestingly, the derivative (m-SF[Formula: see text]PhO)[Formula: see text]PcCu (7b) substituted a SF5group at [Formula: see text]-position showed a Col[Formula: see text](P21/a) ([Formula: see text] p2gg) mesophase from rt to 315.0[Formula: see text]C, whereas the derivative (p-SF[Formula: see text]PhO)[Formula: see text]PcCu (7c) substituted a SF5group at [Formula: see text]-position showed a crystalline (K) phase from rt to the decomposition temperature at ca. 336[Formula: see text]C without showing mesomorphism. Thus, the novel phthalocyanine derivative (m-SF[Formula: see text]PhO)[Formula: see text]PcCu (7b) substituted a strong electron withdrawing SF5group at [Formula: see text]-position shows only one columnar mesophase in a very wide temperature region from rt to 315.0[Formula: see text]C. Furthermore, the Q-band wavelengths (672.2 and 672.1 nm) of the present (m-SF[Formula: see text]PhO)[Formula: see text]PcCu (7b) and (p-SF[Formula: see text]PhO)[Formula: see text]PcCu (7c) are shorter than that (680.3 nm) of the previous [(m-C[Formula: see text])PhO][Formula: see text]PcCu (5c) derivative. It can be attributed to strong electron withdrawing nature of the SF5group on the phenoxy group.

Abstract
The pentafluorosulfanyl (SF5) group is more electronegative, lipophilic and sterically bulky relative to the well-explored trifluoromethyl (CF3) group. As such, the SF5 group could offer access to pharmaceuticals, agrochemicals and optoelectronic materials with novel properties. Here, the first synthesis of phthalocyanines (Pcs), a class of compounds used as dyes and with potential as photodynamic therapeutics, with a SF5 group directly attached on their peripheral positions is disclosed. The key for this work is the preparation of a series of SF5-containing phthalonitriles, which was beautifully regio-controlled by a stepwise cyanation via ortho-lithiation/iodination from commercially available pentafluorosulfanyl arenes. The macrocyclization of the SF5-containing phthalonitriles to SF5-substituted Pcs required harsh conditions with the exception of the synthesis of β-SF5-substituted Pc. The regiospecificity of the newly developed SF5-substituted Pcs observed by UV/Vis spectra and fluorescence quantum yields depend on the peripheral positon of the SF5 group.
