The methods of preparation of functionalized 4-methyl-5-phenylthiazoles (4), (5), (6), (7), (8) and 1,3-bis(4′-methyl-5′-phenylthiazol-2′-yl)benzenes (10), (12), (13), (14), (15) -tetraphenyl-5,6,12,13-tetrathia-1,3,10(2,4),8(4,2)-tetrathiazola-2,9(1,3)-dibenzenacyclotetradecaphane (20) are developed. The homolytic reactions of compounds, containing the fragment CH 2 -S (6), (7), (8), (14), (15) and (20) are considered. Under thermolysis of 1,3-bis(4′-mercaptomethyl-5′-phenylthiazol-2′-yl)benzene (15) the formation of macrocyle (32) take place.
