The adducts (3) of triethylphosphine (1) and several isothiocyanates (2) were prepared. Equilibrium constants of the adducts (5) from tributylphosphine (4) and phenyl (2b), benzoyl (2e), and p-toluenesulfonyl isothiocyanates (2f) were determined in some solvents. The 31P chemical shifts of 5 were measured in DMF, and correlated with Hammett σp constants. Reactions of 3e with 1 and 2e gave phosphonium
制备了三乙基膦 (1) 和几种异硫氰酸酯 (2) 的加合物 (3)。在某些溶剂中测定了来自三丁基膦 (4) 和苯基 (2b)、苯甲酰基 (2e) 和对甲苯磺酰基异硫氰酸酯 (2f) 的加合物 (5) 的平衡常数。5 的 31P 化学位移在 DMF 中测量,并与 Hammett σp 常数相关。3e 与 1 和 2e 的反应分别得到 6 和 7 和 11 的硫氰酸鏻。3e 的甲基化得到 S-甲基 N-苯甲酰基单硫代氨基甲酸酯 (16)。
