with diazomethane and several α-diazo esters to afford α-arylseleno isothiocyanates (5a–10a) and the isomeric thiocyanates (6b–8b) as the major and minor products, respectively. Analogous insertion reactions were observed with benzenesulfenyl thiocyanate (3) and benzeneselenenyl selenocyanate (4) to furnish phenylthiomethyl isothiocyanate (11), ethyl α-phenylthio-α-isothiocyanoacetate (12) and phenylselenomethyl
苯和邻硝基苯硒基亚硫氰酸酯(1和2)与重氮甲烷和几种α-重氮酯反应,得到α-芳基硒代异硫氰酸酯(5a-10a)和异构体硫氰酸酯(6b-8b),为主要产物和次要产物,分别。用硫氰酸benzenesulfenyl(观察到类似的插入反应3)和硒氰酸benzeneselenenyl(4),得到苯硫基甲基异硫氰酸酯(11),乙基α-苯硫基α-isothiocyanoacetate(12)和phenylselenomethyl isoselenocyanate(13),乙基α-phenylseleno-α-异壬基氰乙酸酯(14), 分别。N-(苯基硒代)邻苯二甲酰亚胺形成了插入产物N-(苯基硒代甲基)邻苯二甲酰亚胺(16)和α-苯基硒代-α-邻苯二甲酰亚胺基乙酸乙酯(17),并带有重氮甲烷和重氮乙酸乙酯,但消除了相应的乙烯基硒化物α-(苯基硒代)乙基用含β-氢的重氮酯处理时,可得)丙烯酸酯(18)和2
