DOI: 10.1016/j.jorganchem.2019.120998
Abstract: Abstract The synthesis of an unsymmetrical silyl-ether-modified 1-oxazolinyl 1,2′-bis(diphenylphosphine) ferrocene is proposed herein. The designed 1,2′-bisphosphine is generated from 1-bromo-l’-carboxyferrocene in six synthetic steps in moderate yield with high diastereoselectivity. Moreover, a 2,5-bisphosphine analog is… read more here.

DOI: 10.1021/acs.macromol.8b02741
Abstract: Metal-free hydrosilylation using tris(pentafluorophenyl)borane (B(C6F5)3) as a catalyst enables the rapid polymerization of α-diketone and bis(silane) monomers under ambient conditions to give high molecular weight poly(silyl ether)s (PSEs). A wide selection of commercially available monomers… read more here.

Abstract: Substituted 9-methyldecalin derivatives containing an all carbon quaternary chiral center were synthesized with excellent enantioselectivity via an organocatalyst-mediated domino reaction. The first reaction is a diphenylprolinol silyl ether-mediated Michael reaction, and the second reaction is… read more here.

DOI: 10.1021/jacs.2c11858
Abstract: Convenient strategies for the deconstruction and reprocessing of thermosets could improve the circularity of these materials, but most approaches developed to date do not involve established, high-performance engineering materials. Here, we show that bifunctional silyl… read more here.
