Deprotection of N-benzylbenzimidazoles and N-benzylimidazoles with triethylsilane and Pd/C

The benzyl group is a protecting group for benzimidazoles and imidazoles that can survive acidic, basic, oxidizing, and reducing conditions. Deprotection, however, can require vigorous and potentially non-chemoselective methods. The triethylsilane–Pd/C reduction system is an exceptionally mild, convenient, and efficient method for deprotecting N-benzylbenzimidazoles that are unsubstituted at the 2- and 4-positions as well as suitably substituted N-benzylimidazoles.

Color developing agent, processing composition and color image-forming method

A method for forming a color image comprises the step of developing an image-wise exposed silver halide color photographic photosensitive material at the presence of a 6-aminotetrahydroquinoline color developing agent which is the following compound or its analoge. According to this method, the rapid process can be attained and an image of a low fog density can be obtained. STR1
