求教关于二苯乙酮的氯化
C6H5-CO-CH2-C6H5 氯化成 C6H5-CO-CCL2-C6H5
用氯气氯化,是用碱催化剂,还是酸催化剂,或者怎样防止水解成,二苯乙二酮C6H5-CO-CO-C6H5

请问这位大哥,用碱作催化剂具体如何使用,是使碱的水溶液?%,还是固体片碱,会不会水解成二苯乙二酮

The reaction of 2-(4-methoxyphenyl)-4-chromanone with Mn(OAc)3 in the presence of LiCl gave 3,3-dichloro-2-(4-methoxyphenyl)-4-chromanone.The reactions of 2-phenyl-4-chromanone, 1-phenyl-1-propanone, 1,2-diphenylethanone, and 1-tetralone similarly yielded ,-dichloro derivatives in good yields. 2,2,2-Trichloroacetophenones were obtained from 2,2-dichloroacetophenones, but in the absence of LiCl, 2,2-dichloroacetophenones gave 2,2,3,3-tetrachloro-1,4-butanediones.KCl, NaCl, NH4Cl,AlCl3, and CaCl2 were also employed as the Cl- ion source.Synthetic applicability and the reaction mechanisms are discussed briefly.
