Au(Ⅰ)配合物催化剂室温高效催化炔烃水合反应

Au(Ⅰ) Complexes as the Efficient Catalyst for Hydration of Alkynes at Room Temperature

合成了一系列（1,1＇-联苯）-2-二（1-金刚烷基）磷配体,并制备出8种相应的Au（Ⅰ）配合物.以甲醇为溶剂,在6-十二炔水合反应中考察了8种Au（Ⅰ）配合物的催化性能,结果表明,以含有3＇-（吡咯-1-羰基）官能团的Au（Ⅰ）配合物为催化剂时,其用量仅需炔烃用量的0.1%-0.3%（摩尔分数）,室温下即可高效地催化炔烃进行水合反应.

A series of （ 1,1 ＇-biphenyl） -2-yldi （adamantan-l-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-l-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.
