Abstract

The halogenation of Lewis-acid/base-stabilised phosphanylboranes ( 1a) and arsanylboranes ( 1b) with CX4 (X = Cl, Br) leads selectively to the substitution of both protons at the pentel atom and the new compounds [(CO)5W(X2PBH2·NMe3)] ( 2a: X = Cl, 2b: X = Br) and [(CO)5W(X2AsBH2·NMe3)] ( 3a: X = Cl, 3b: X = Br), respectively, are obtained. The new products were comprehensively characterised by ...
