A gem-aluminium(iii)/antimony(iii) C centre incorporated in a bimetallic six-membered heterocycle

Abstract

Reaction of AlMe₃ with the implied stibene intermediate (–Sb=C[double bond splayed left]) formed in the reaction of [(2-pyr)(SiMe₃)₂CLi·tmeda] with SbCl₃ affords the carboalumination product containing a gem-Al/Sb C centre as part of a six-membered heterocycle, [(2-pyr)(SiMe₃)₂C–Sb(Me)–(2-pyr)(SiMe ₃)C–Al(Me)₂] 1, structurally authenticated as the (RS,SR) diastereoisomer.
