Abstract:

A series of (1,1'-biphenyl)-2-yldi(adamantan-1-yl) phosphine ligands was synthesized to prepare eight kinds of Au(Ⅰ) complexes. And their catalytic performances were investigated in the hydration of alkynes using methanol as solvent. At room temperature, it was found that Au(Ⅰ) complexes containing the group of 3'-(pyrrolidin-1-ylcarbonyl) showed the excellent catalytic performance in the hydration of alkynes with the catalyst loading of 0.1%―0.3%(molar fraction, base on alkynes). The reaction parameters were further optimized for spreading the applied scope of the catalysts. Therefore, a mild catalytic system with good applicability was explored for the hydration of terminal and internal alkynes using less dosage of catalyst.
