Abstract 1-Alkynyl 2-alkynyl sulfides, R 1 C [TRIPLE BOND] C [BOND] S-CH 2 C [TRIPLE BOND] CR 2, 1, rearrange at room temperature (if R 2= H) or upon heating (if R 2= alkyl). The thioketenes, H 2 C [DOUBLE BOND] C [DOUBLE BOND] C (R 2)-C (R 1)[DOUBLE BOND] C [DOUBLE BOND] S, 2, presumed to be formed can be trapped by secondary amines, or-in some cases-by dialkylphosphines. Depending upon the nature of the ...
