We have developed new complexes of the type [NiiPrHNC(S)NP(S)(OiPr)2-1,3-N,Sâ²}2]/PR3 (R3 = Me3, Me2Ph) for the generation of Ni0 catalysts which can be used for the catalytic addition of Ph2S2 to 1-, 2- and 3-hexynes. A detailed study of the catalytic reaction mechanism suggests two possible pathways for the in situ formation of Ni0 species, depending on the presence or absence of water.
我们开发了新型复合物[NiiPrHNC(S)NP(S)(OiPr)2-1,3-N,S'}2]/PR3(R3 = Me3, Me2Ph),可用于生成Ni0催化剂,这些催化剂能够催化Ph2S2与1-、2-和
3-己炔的加成反应。对催化反应机理的详细研究表明,根据
水是否存在,可能存在两种不同途径用于原位生成Ni0物种。
