Synthesis and Chemical Properties of Benzo[e]-1,2-Oxaphosphorinine Derivatives—Analogues of Coumarins
摘要:
The 4-aryl(alkyl)benzo[e]-1,2-oxaphosphorine derivatives (phosphacoumarins) were obtained by the reaction of 2,2,2-trihalogenobenzo[d]-1,3,2-dioxaphospholes with terminal acetylenes. The reactions of phosphacoumarins with halogens and Grignard reagents were investigated.
