S. Abbas et al., The 'Hirao reduction' revisited: a procedure for the synthesis of terminalvinyl bromides by the reduction of 1,1-dibromoalkenes, TETRAHEDR L, 41(17), 2000, pp. 3215-3219
A convenient procedure for the synthesis of vinyl bromides is described, wh
ich involves the selective reduction of the corresponding 1,1-dibromoalkene
s with dimethylphosphite and triethylamine. The 1,1-dibromoalkenes are obta
ined in excellent yields from the corresponding aldehydes via olefination w
ith carbon tetrabromide and triphenylphosphine. (C) 2000 Elsevier Science L
