Abstract
Treatment of N-tosyl aldimines with dialkyl trimethylsilyl phosphites at 0 degrees C in the presence of iodine as a catalyst afforded the corresponding sulfonamide phosphonates in excellent yields within 1.5 to 2.5 h.
摘要
在0℃下，以碘为催化剂，用二烷基三甲基甲硅烷基亚磷酸酯处理N-对甲苯磺酰基醛亚胺，在1.5至2.5小时内以优异的产率得到相应的磺酰胺基膦酸酯。
