The reaction of ortho-lithiated N,N-dimethyl-1-arylethyl-amines with triphenyl- boron leads, with elimination of phenyllithium, to (R)-(−)-2,2,3-trimethyl-1,1-diphenyl -1H-2-azonia-1-borata-indene (1), 2,3-dihydro-1,1,2-trimethyl-3,3-diphenyl- 1H-2-azonia-3-borata-benz[e]indene (2) and 2,3-dihydro-2,2,3-trimethyl-1,1-diphenyl -1H-2-azonia-1-borata-benz[e]indene (3) with a strongB←N bond. 1, 2 and 3
的反应邻-lithiated N,N-二甲基-1-芳基乙基-胺与三苯基硼引线,与消去苯基锂,对([R )- ( - ) - 2,2,3-三甲基-1,1-二苯基-1 H -2- azonia-1-borata-茚(1),2,3-二氢-1,1,2-三甲基-3,3-二苯基-1 H -2- azonia-3-borata-benz [ e ] indene(2)和具有强B←的2,3-二氢-2,2,3-三甲基-1,1-二苯基-1 H -2- azonia-1-borata-benz [ e ] indene(3) N键。1,2和3对氧气,水和酒精稳定。通过使三苯基硼与一些被供电子基团取代的芳基锂化合物反应,形成对相同试剂敏感的三芳基硼化合物。
