Abstract

Aminoacetylenes R2N-C ≡ C-R’ (1) afforded 2,4-dialkylidene-1,3-dithietanes (2) on compressing or heating with carbon disulfied. The structure of 2 was determined by X-ray crystal structure analysis. Thiocarbamoylthioketenes, 1:1 adducts of the ynamine and carbon disulfide were proposed as the probable intermediates leading to 2. The present results indicate that the reactivities of ynamines toward carbon disulfide are different from those of electron-deficient acetylenes.
