The hydroboration of bis(trimethylsilyl)ethyne, Me3Si-C≡C-SiMe3 1, with 9-borabicyclo [3.3.1] nonane (9-BBN) gives first the expected (Z)-alkene 5 which rearranges, without UV irradiation, after several days quantitatively into the (E)-alkene 6. Heating of 6 in the presence of a further equivalent of 1 leads, again almost quantitatively, to an allene, the 1… (More)
