Abstract
S , S '-Dialkyl N -(arenesulfonyl)carbondithioimidates 3 are prepared either in a one-pot reaction by successive alkylation of disodium salts 2 or by using N -(arenesulfonyl)dithiocarbamates 4 . C,H-Acidic N -(arenesulfonyl)-carbondithioimidates 3a , b , d react with thiacumulenes in the presence of sodium hydride. Subsequent methylation leads to 2,3-dihydrothiazoles 7 and 1,3-dithiols 8 , respectively.
S, S '-二烷基N -(芳烃磺酰基)二硫代氨基甲酸酯可以通过二钠盐的连续烷基化在一锅反应中制备，也可以用N -(芳烃磺酰基)二硫代氨基甲酸酯4制备。C, h -酸性N -(arenesulfonyl)-碳二硫代酸盐3a, b, d在氢化钠存在下与噻唑烯反应。随后的甲基化分别生成2,3-二氢噻唑7和1,3-二硫醇8。
