Abstract

A new synthetic pathway to various mono-alkyl-substituted phosphinoboranes HRP–BH2–NMe3 has been developed. The new synthetic route starting from alkyl halides and NaPH2 followed by metalation and salt metathesis is performed in a one-pot procedure and leads to higher yields and purity of the resulting phosphinoboranes, as compared to previously reported routes. Additionally, the scope of ...
