Hydroalumination of dialkynylgermanes—synthesis of alkenyl–alkynylgermanes with intramolecular aluminium–carbon interactions†‡
Abstract
Reactions of dialkylaluminium hydrides, R2AlH [R = CH2CMe3, CMe3, C–C6H5)2 [R = CH3 (1), C6H5 (2)], afforded mixed alkenyl–alkynylgermanes, R2Ge(C
C–C6H5)[C(AlR2)
C(H)–C6H5] (3 to 7), by hydroalumination of one of the
C
C double bond was observed. Crystal structure determinations revealed relatively strong intramolecular bonding interactions between the coordinatively-unsaturated aluminium atoms and the
