An air-stable rhodium(I)-oxygen adduct featuring a CNC-pincer ligand, based on 1,2,3-triazol-5-ylidenes, catalyzes the homo-dimerization and hydrothiolation of alkynes, affording the gem-enyne and α-vinyl sulfide isomers, respectively, with excellent selectivity. A one-pot stepwise strategy allows the selective catalytic preparation of non-symmetric bis-vinyl sulfides, as well as the alkyne dimerization-hydrothiolation tandem reactions.
一种基于1,2,3 - 三唑 - 5 - 亚基的、具有CNC钳形配体的空气稳定铑（I） - 氧加合物，可催化炔烃的均二聚反应和氢硫基化反应，分别以优异的选择性得到偕二烯炔和α - 乙烯基硫醚异构体。一锅分步策略允许选择性催化制备不对称双乙烯基硫醚，以及炔烃二聚 - 氢硫基化串联反应。
