摘要

Summary: A convenient synthesis of the easily handled, crystalline oxonium acid [(3, 5- (CF3) 2C6H3) 4B]-[H (OEt2) 2]+(1) is described. The utllity of this reagent for generatlon and stabilization of highly electrophilic cationic transltlonmetal complexes through protonation reactions is iiiustrated by the preparation of stable, ether-free salts of from C, Me5 (P (OMe) 3) Co (C2H,). The incorporation of the noncoordinatlng counterion [(3, 5-(CF3), C, H3), B]- ...
