Bromoboration of l-hexyne with BBr, followed by treatment with 2-propanol produced alkenyl boronic ester 3. Subsequent Pd(O)-catalyzed cross-coupling with acetylenic zinc chlorides and iodination furnished enyne iodides 6, which were then converted to enyne-allenes 8 by a second Pd(O)-catalyzed reac

a-Lithiated (trimethylsilyloxy)butatrienes, generated by 1,4-elimination of methanol from l-trimethylsilyloxy-4-methoxy-2-alkynes with :=rt-butyllithium, give mixtures of cr-allenic aldehydes and allenyl trimethylsilyl ketones which can be separated by distillation. The ratio aldehyde/ketone is solv
