, p. 2371 - 2382 (2007/10/02)
By reaction of the aminoacetylides 2 with alkyl and aryl isothiocyanates 3 the 3-aminopropiolthioamides 5 are formed.Benzyl and allyl bromides 6 alkylate these ynamines at the sulfur atom thus forming the S-alkyl 3-aminopropiolthioimidates 7.Hydrogen sulf
Aminoethynyl Metallations, 15. - S-Stannyl 3-Aminopropiolothioimidates
Himbert, Gerhard
, p. 1669 - 1678 (2007/10/02)
The reaction of the (stannylethynyl)amines 1 with aryl isothiocyanates (2) furnishes the S-stannyl 3-aminopropiolothioimidates 4.The S-trimethylstannyl derivatives of 4 react with water, acid chlorides, or phenyl isocyanate to give the ynamine carbothioamides 5, the N-acylynamine carbothioamides 7, and the 4-(aminomethylene)-5-thioxo-2-imidazolidinones 8.The reaction of the N,N-diethylynamine 4a with diphenylketene gives the cyclobutenone 6 by cycloaddition.
