Metal-Free Addition/Head-to-Tail Polymerization of Transient Phosphinoboranes, RPH-BH2 : A Route to Poly(alkylphosphinoboranes) (original) (raw)

Angewandte Chemie (International ed. in English), 2015

Abstract

Mild thermolysis of Lewis base stabilized phosphinoborane monomers R(1) R(2) PBH2 ⋅NMe3 (R(1) ,R(2) =H, Ph, or tBu/H) at room temperature to 100 °C provides a convenient new route to oligo- and polyphosphinoboranes [R(1) R(2) P-BH2 ]n . The polymerization appears to proceed via the addition/head-to-tail polymerization of short-lived free phosphinoborane monomers, R(1) R(2) P-BH2 . This method offers access to high molar mass materials, as exemplified by poly(tert-butylphosphinoborane), that are currently inaccessible using other routes (e.g. catalytic dehydrocoupling).
