Suzuki–Miyaura catalyst-transfer polycondensation of triolborate-type fluorene monomer: toward rapid access to polyfluorene-containing block and graft copolymers from various macroinitiators

We demonstrated that the Suzuki–Miyaura catalyst transfer polycondensation of a triolborate-type fluorene monomer can be an efficient and versatile approach to the synthesis of polyfluorenes (PFs) and PF-containing block and graft copolymers.

A General and Air-tolerant Strategy to Conjugated Polymers within Seconds under Palladium(I) Dimer Catalysis

While current M0 /MII based polymerization strategies largely focus on fine-tuning the catalyst, reagents and conditions for each and every monomer, this report discloses a single method that allows access to a variety of different conjugated polymers within seconds at room temperature. Key to this privileged reactivity is an air- and moisture stable dinuclear PdI catalyst. The method is operationally simple, robust and tolerant to air.

Controlled Pd(0)/Ad3P-Catalyzed Suzuki Cross-Coupling Polymerization of AB-Type Monomers with Ad3P-Coordinated Acetanilide-Based Palladacycle Complex as Initiator

Controlled Pd(0)-catalyzed Suzuki cross-coupling polymerizations of AB-type monomers with tris(1-adamantyl)phosphine (Ad₃P) as the ligand was described. Ad₃P-coordinated acetanilide-based palladacycle complex (1) was demonstrated to be an efficient initiator for controlled Suzuki cross-coupling polymerization, affording polymers with narrow Đs and well-controlled end groups. Our study provided an efficient ligand and an efficient initiator for controlled Suzuki cross-coupling polymerizations.

Synthetic approaches towards structurally-defined electrochemically and (photo)redox-active polymer architectures

This review details synthetic strategies leading to structurally-defined electrochemically and (photo)redox-active polymer architectures,e.g.block, graft and end functionalized (co)polymers.

t-Bu3P-Coordinated 2-Phenylaniline-Based Palladacycle Complex/ArBr as Robust Initiators for Controlled Pd(0)/t-Bu3P-Catalyzed Suzuki Cross-Coupling Polymerization of AB-Type Monomers

t-Bu₃P-coordinated 2-phenylaniline-based palladacycle complex (1) as the unique source of Pd(0)/t-Bu₃P to form efficient initiators with ArBr for controlled Suzuki cross-coupling polymerizations of AB-type monomers was described. The in situ generated initiators were demonstrated to be robust initiator systems for controlled Suzuki cross-coupling polymerization, affording polymers with unprecedentedly narrow PDIs and well-controlled functional end groups. ³¹P NMR study suggested that the fast and efficient generation of ArPd(t-Bu₃P)Br complexes from precatalyst 1 and ArBr might be the reason for better control of polymerization with precatalyst 1/ArBr as initiators. Our study provided a family of unprecedented, highly efficient initiators for controlled Suzuki cross-coupling polymerizations and a direct route to access conjugated polymers with a variety of heterobisfunctional chain end groups.
