α-Chloroalkyl and α-bromoalkyl carbonates have been prepared by cleavage of α-arylthioalkyl carbonates with sulfuryl chloride or bromine, respectively. The α-arylthioalkyl carbonates are prepared by reaction of the hemithioacetal 1 with chloroformates or by a destannylative tin-Pummerer rearrangement of α-stannyl sulfoxides.

Process for the preparation of 1'-ethoxy carbonyloxy ethyl esters of penicillins, wherein a compound of the formula STR1 in which A is phenyl, phenoxy or 4-hydroxyphenyl, B is hydrogen, an amino group or a protected amino group and Z is hydrogen or a cation selected from the group of alkali metal, tri (lower alkyl ) ammonium and tetra (lower alkyl) ammonium, is reacted with 1-bromoethyl ethyl carbonate in an organic solvent and when B is a protected amino group the protecting group is split off to yield a primary amino group. There are also provided novel compounds of the formula STR2 in which Ph is phenyl and R is CH3 -- or C2 H5 --.
