No metallation of the benzylic CH bonds was detected when n-butyllithium reacted at −78°C with methyl-, fluoromethyl- and difluoromethyl- -pentafluorobenzene. The isolated product, in each case, was the para- substituted butyl toluene; respectively, 1-n-butyl-4-methyl-, -4-fluoromethyl-, and -4-difluoromethyl-tetrafluorobenzene.
当正丁基锂在-78°C下与甲基,氟甲基和二氟甲基-五氟苯反应时,未检测到苄基CH键的金属化。在每种情况下,分离出的产物是对位取代的丁基甲苯。分别是1-正丁基-4-甲基-,-4-氟甲基-和-4-二氟甲基-四氟苯。
