Ar. Amamchyan et al., SYNTHESIS OF TRICYCLIC COMPOUNDS WITH A 4-COORDINATE BORON ATOM FROM 2-AMINOBENZAZOLES AND NITRILES, Russian chemical bulletin, 45(4), 1996, pp. 974-976
The reactions of 2-aminobenzazoles with nitriles in the presence of or
ganoboranes result in the formation of novel tricyclic chelate boron c
ompounds with N-(benzazol-2-yl)amidines as ligands. N-(Benzothiazol-2-
yl)-p-chlorobenzamidine was prepared from 2-aminobenzothiazole and p-c
hlorobenzonitrile via the corresponding chelate.
