Изобретение относитс к органической химии , а именно к новому способу получени ОКСИ- или алкоксидифенилциклоалкилметанов общей формулыThis invention relates to organic chemistry, in particular to a new method for the preparation of oxy- or alkoxydiphenylcycloalkylmethanes of the general formula
((
( (I)((I)
где л- 1, 2;where l - 1, 2;
R - ОКСИ- или алкоксигруппа.R is OXI or alkoxy.
Способ получени окси- или алкоксидифенилциклоалкилметанов в литературе не описан .The method for producing hydroxy- or alkoxydiphenylcycloalkylmethanes is not described in the literature.
С целью синтеза окси- или алкоксидифенилциклоалкилметанов общей формулы (I) предлагаетс способ их получени путем взаимодействи окси- или алкоксибензола с 1-бензилциклоалкеном в присутствии катализатора ВРз-НзРО4 и растворител четыреххлористого углерода.In order to synthesize hydroxy or alkoxydiphenylcycloalkylmethanes of the general formula (I), a method for their preparation is proposed by reacting hydroxy or alkoxybenzene with 1-benzylcycloalkene in the presence of a BPH-H3PO 4 solvent and carbon tetrachloride solvent.
Реакцию обычно провод т в избытке оксиили алкоксибензола.The reaction is usually carried out in an excess of hydroxy or alkoxybenzene.
Целевые продукты выдел ют известными приемами с выходом 80-88%.Target products are isolated by known methods with a yield of 80-88%.
Процесс предпочтительно провод т при соотношении окси- или алкоксибензола, 1-бензилциклоалкена , катализатора и растворител 4-5 : 1 : 0,3 : 1-5.The process is preferably carried out at a ratio of hydroxy or alkoxybenzene, 1-benzylcycloalkene, catalyst and solvent 4-5: 1: 0.3: 1-5.
Сущность происход щих превращений св зана с перегруппировкой промежуточно образующихс неустойчивых в этих услови х третичных бензилциклоалкилкатионов во вторичные фенилциклоалкилметилкатионы, более стабильные за счет сопр жени с ароматическим дром, и идет по схеме:The essence of the transformations occurring is associated with the rearrangement of intermediately formed tertiary benzylcycloalkylcations, which are unstable under these conditions, into secondary phenylcycloalkylmethylcations, which are more stable due to conjugation with the aromatic core, and follows this scheme:
