Yao, Wei-Wei published the artcileNi-catalyzed hydroaminoalkylation of alkynes with amines, Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is Nature Communications (2021), 12(1), 3800, database is CAplus and MEDLINE.
Here, a late transition metal Ni-catalyzed hydroaminoalkylation of alkynes RCCR1 (R = Me, n-Bu, Ph, 4-methoxyphenyl, etc.; R1 = Me, i-Pr, TMS, 4-ethylphenyl, etc.) with N-sulfonyl amines R2CH2NHR3 (R2 = pentyl, cyclohexyl, Ph, thiophen-2-yl, 2H-1,3-benzodioxol-5-yl, etc.; R3 = Ms, Ts, [2,4,6-tris(propan-2-yl)phenyl]sulfonyl, etc.), providing a series of allylic amines R2CH(NHR3)C(=CHR1)(R) in up to 94% yield was reported. Double ligands of N-heterocyclic carbene (IPr) and tricyclohexylphosphine (PCy3) effectively promote the reaction.
