Terminal alkynes with secondary amines (dimethylamine, diethylamine, piperidine, morpholine) and CO2 in the presence of mononuclear ruthenium catalysts, afford the vinyl carbamates R1CHCHOCONR2. The reaction studies suggest, as the active catalytic species, a ruthenium-vinylidene intermediate.
在单核钌催化剂的存在下,末端炔与仲胺(二甲胺,二乙胺,哌啶,吗啉)和CO 2,得到氨基甲酸乙烯基酯R 1 CH = CH = O = CONR 2。反应研究表明,钌-亚乙烯基中间体作为活性催化物质。
