An <i>N</i>-phosphinoamidinato borasilenide: a vinyl-analogous anion containing a base-stabilised B[double bond, length as m-dash]Si double bond.

ABSTRACT: Borasilenes, which feature a heterodinuclear Si[double bond, length as m-dash]B double bond, show interesting reactivities, due to two proximal reactive sites-boron and silicon-each with distinct electronic properties. However, borasilenes remain relatively rare due to the challenge of stabilising them. To achieve a stable borasilene, both the boron and silicon centers must be supported by sterically hindered ligands, which can, however, interfere with their potential applications. In this work, we report the synthesis of an N-phosphinoamidinato potassium borasilenide (compound 3), which is a vinyl-analogous anion containing a base-stabilised B[double bond, length as m-dash]Si^- double bond. This B[double bond, length as m-dash]Si^- double bond is functional and
