base hydrolysis of cobalt(iii)
... If the S N 2 reaction were correct then the role of OH would be to attack cobalt and form [Coen 2 NO 2 (OH)]+ (Eq. 13). Clearly that is not the role of OH - , because [Coen 2NO 2 (OH)]+ does not react with NO 2- (Eq. 15). However, a mixture of [Coen 2 NO 2 Cl], NO 2 - , and OH readily afford [Coen 2 ...
