A direct method for the synthesis of 1,2,5-triaryl-1H-imidazoles was achieved easily from cyclization of aryl acetaldehydes with amidines catalyzed by I2. Various substitued groups can be employed, and this reaction proceeds smoothly in moderate to good yields.

A large variety of 1,2-diaryl-1H-imidazoles, including a selective COX-2 inhibitor, have been regioselectively synthesised in moderate to high yields by direct coupling of 1-aryl-1H-imidazoles with aryl iodides or bromides in DMF in the presence of CsF an

Primary ureas have been used as substrates in rhodium-catalyzed N-H insertion reactions with an array of diazocarbonyls. The insertion reaction is efficient and gives excellent selectivity and yields. The products from the insertion reaction with diazoket
