Selective monoalkylation of phosphorus-substituted CH acids with (bromomethyl)- and 1,4-bis(bromomethyl)benzenes
摘要:
C-Alkylation of phosphorus-substituted CH acids with various substituted (bromomethyl)arenes under phase transfer catalysis conditions (K2CO3/MeCN) proceeds with high selectivity (75-100%) as monoalkylation.
