PMID: 30869102
Dalton Trans. 2019 Apr 09;48(15):4846-4856. doi: 10.1039/c9dt00484j.

Three polymeric versions of ansa-N,N-dialkylammoniumtrifluoroborate ambiphilic molecules based on the styrene motif (poly(1-NMe2H+-2-BF3--4-styrene) (P-Me), poly(1-NEt2H+-2-BF3--4-styrene) (P-Et) and poly(1-piperidinyl-H+-2-BF3--4-styrene) (P-Pip)) were synthesized, characterized and tested as heterogeneous pre-catalysts for the borylation of electron-rich heteroarenes. These heterogeneous versions of previously reported...

PMID: 29776140
Phys Rev E. 2018 Mar;97(3):032502. doi: 10.1103/PhysRevE.97.032502.

We consider the complex polymer system, consisting of a ring polymer connected to the f_{1}-branched starlike structure, in a good solvent in the presence of structural inhomogeneities. In particular cases f_{1}=1 and f_{1}=2, such a system restores the synthesized...

Angew Chem Int Ed Engl. 2021 Dec 20;e202112966. doi: 10.1002/anie.202112966. Epub 2021 Dec 20.

Syndioselective polymerization of unprotected polar styrenes has achieved great success via specially designed catalysts and the establishment of "self-assisted" theory. In contrast, isospecific polymerization of polar styrenes has remained less explored. Herein, we present new racemic ansa-bis(benz[e]indenyl) rare-earth metal...
