Efficient synthesis and catalysis of a series of palladium complexes having a group 13 metalloligand (Al, Ga, In) are reported utilizing 6,6″-bis(phosphino)terpyridine as a new scaffold for Pd-E bonds (E = Al, Ga, In). Systematic investigation revealed unique characteristics of the Al-metalloligand in both structure and reactivity, which exhibited the highest catalytic activity for hydrosilylation
据报道,利用 6,6"-双(膦基)三联吡啶作为 Pd-E 键 (E = Al, Ga) 的新支架,高效合成和催化一系列具有第 13 族金属配体 (Al, Ga, In) 的钯配合物, 在)。系统研究揭示了铝金属配体在结构和反应性方面的独特特征,其对 CO2 氢化硅烷化的催化活性最高(TOF = 19 300 h-1)。该研究表明,通过精确设计的金属配体对催化剂活性进行微调是合成有机金属化学中新催化剂开发的一种有前途的方法。
