Organoborierung von Alkinylstannanen, VI [1] Allenbildung bei einer Deorganoborierung / Organoboration of Alkynylstannanes, VI [1] Formation of an Allene by Deorganoboration

Abstract

Abstract The thermal decomposition of some 1,1-bis(trimethylstannyl)-2-dialkylborylalkenes leads unexpectedly to substituted allenes. The structural information is based on 1H, 11B, 13C and 119Sn NMR data and also on the strong IR band at 1882 cm-1.
