โœฆ Synopsis

A family of organic polychalcogenides with a common structure of RSeS x SeR (with x=1, 2, 3 and R=CH 3 , Ph, PhCH 2 , O 2 NC 6 H 4 CH 2 ) as well as cyclic 5,5-dimethyl-1,2-dithia-3,7-diselenacycloheptane were synthesized in good yield and high purity from the reaction of Ph 3 CS x Cl with corresponding diselenides in chloroform at room temperature. Mechanistic aspects of the insertion involving the formation of an intermediate (RSeS x CPh 3 ) are discussed.

## Enynones are converted to phenols by an acid catalyzed process which can be controlled to give either of two regioisomeric series of products. During the course of efforts aimed at converting the acetylenic enone 1 to the acorone precursor 2,l.z we were surprised to find that collidine p-toluen
