前已报道,碱性较强的试剂如RO-M~+(R=C_2H_5,C_6H_5,C_6F_5等)与二氟甲磺酰氟HCF_2SO_2F(1)作用时,除进攻硫原子得到HCF_2SO_3R(2)外,还可攫氢产生二氟卡宾而得到HCF_2OR(3)和HCF_3(4).
It has been previously reported that strong alkaline reagents such as RO-M ~ + (R = C_2H_5, C_6H_5, C_6F_5, etc.) interact with difluoromethanesulfonyl fluoride HCF_2SO_2F (1) Hydrocarbons can also be generated by hydrogenation to produce difluorocarbene HCF_2OR (3) and HCF_3 (4).
