A concise synthetic protocol for aryl functionalized phenanthrolines has been developed. It was demonstrated that 3,8-diphenyl-1,10-phenanthroline (7a) is competent in promoting transition-metal-free direct arylation and 2,3,8,9-tetraphenyl-1,10-phenanthroline (8a) is a highly efficient ligand in the in situ Pd-catalysed Heck reaction.
已开发出一种简明的合成芳基取代的菲纳烯类化合物的协议。研究表明,3,8-二苯基-1,10-菲纳烯 (7a) 能有效促进无金属催化的直接芳基化反应,而2,3,8,9-四苯基-1,10-菲纳烯 (8a) 在原位钯催化的Heck反应中是一种高效的配体。
