Dinuclear palladium complexes bridged by a novel PNNP ligand, N,N′-bis[(2-diphenylphosphino)phenylformamidinate (dpfam), were found to be very efficient and selective catalysts for the double carbonylation of iodobenzene with diethylamine using K3PO4 as base and 1,4-dioxane as solvent with a TON up to 105 and selectivity of 96%.
已发现由新型PNNP配体N,N'-双[(2-二苯基膦基)苯基甲ami酸盐(dpfam)桥接的双核钯络合物是非常有效的选择性催化剂,可使用K 3 PO 4作为二乙胺与二乙胺进行双羰基化反应。碱和1,4-二恶烷作为溶剂,TON高达10 5,选择性为96%。
