The CrCl 2 -mediated two-carbon halo-homologation of aryl, alkenyl, and aliphatic aldehydes with chloral ethyl hemiacetal or bromal affords (Z)-a-chloro-and (Z)-a-bromo-a,b-unsaturated aldehydes, respectively, in good to excellent yields and high stereoselectivity. The utility of this methodology wa
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
