Reaction of methyl- and phenylthiomethylidene phosphoranes 1 and 2 with a variety of reducing sugars has been explored. Furano-type carbohydrates afforded with good yields the corresponding open-chain vinyl sulfides, whereas pyrano derivatives produced elimination compounds together with the expected vinyl sulfides, depending on the nature of the protective groups.

In order to elucidate preferred conformations in chalkogen-substituted phosphorus ylides, the title compound (C6H5)3P=C(SC6H5)SeC6H5 (4) has been prepared from (chloromethyl)phenylsulfide (1) via triphenylphosphorane (3). 4 is trans

New 3-(substituted) vinyl cephalosporin compounds, e.g., 3-(2'-ethoxycarbonylvinyl)-7-phenoxyacetamido-3-cephem-4-carboxylic acid, which are useful as antibiotics, and 3-(substituted) vinyl cephalosporin compounds which are useful as intermediates in preparing antibiotic substances.
