, p. 10407 - 10413 (2021)
A base-mediated semihydrogenation of ynamides using p-toluenesulfonyl hydrazide as an inexpensive and easy-to-handle hydrogen donor is reported. This transition-metal-free protocol avoids overhydrogenation and reduction of other functional groups, generating the thermodynamically unfavorable Z-enamides exclusively.

Nickel-catalyzed decarbonylative thioetherification of acyl fluorides has been developed. This transformation allows an array of acyl fluorides to react with thiophenols. A wide range of functional groups are well tolerated and the corresponding sulfides can be obtained in good to excellent yields. This protocol provides the formation of diverse carbon-sulfur bonds via a highly efficient decarbonylative process.
Anti-Markovnikov stereoselective hydroamination and hydrothiolation of (hetero)aromatic alkynes using a metal-free cyclic trimeric phosphazene base
Zhao, Na,Lin, Chengdong,Wen, Lirong,Li, Zhibo
, p. 3432 - 3440 (2019/05/15)
Hydroamination and hydrothiolation are the most efficient and completely atom-economical process to construct important enamine and vinyl sulfide intermediates in pharmaceutical and organic chemistry. The cyclic trimeric phosphazene base (CTPB) showed gre
