The hydrohalogenation reaction of 1,2-allenic sulfoxides 1 afforded 2-haloallyl sulfoxides 2 with yields ranging from 56 to 89%. The influence of the ratio of AlCl 3 and H 2 O on this reaction is discussed and the optimized ratio of allenic sulfoxides, AlCl 3 and H 2 O is 1:0.55:1. For the hydroiodi

Reactions of Cephalosporin Sulfones. Part 2. Rearrangement of 2ฮฑ-Bromocephem Sulfones to Pyrroles. -Two different "rearrangements" of the known bromocephem (I) are observed on standing in different solvents. The mechanistical explanations base on the inverse polarity of the C 2 -Br bond (ฮด + at Br)
