Bis(phenylethynyl)silanes reacted with equimolar quantities of various dialkylaluminium hydrides, R2Al–H [R = CH2tBu, tBu, iBu, CH(SiMe3)2], by hydroalumination and addition of a Al–H bond to a C≡C triple bond. Alkenyl-alkynylsilanes were formed, which had the aluminium atoms in geminal positions with the silicon atoms and adopt a cis arrangement of aluminium and hydrogen at the resulting C=C double
