A comparative study of the behaviour of N-trimethylsilyl and N-neopentyl-anilines and 1,2-diaminobenzenes towards trimethylalane; X-ray structures of nine Al–N compounds
Abstract
The reactions of a pair each of monosubstituted anilines PhNHR1 and disubstituted 1,2-diaminobenzenes C6H4(NHR1)2-1,2 (R1
