新型磷杂环辛二烯的合成及其反应研究

Study on the Synthesis and Reactions of New Phosphocins

本文应用高位阻二酚1与二氯苯基膦和三氯氧磷反应,分别得到了新型磷杂环辛二烯2a和2b,并经IR、~1HNMR、^(31)PNMR.MS和元素分析的证实.研究了化合物2a和2b的立体化学及2a与联苯酰的反应.

New bis[ 2'-t-butyl-4'-methyl-(d, g) benzo] -2-phenyl-l,3,2-dioxaphosphacyclo-octadiene (2a) and bis [2'-t-butyl-4'-methyl-(d, g) benzo]-2-hydroxy-2-oxy-1,3,2-dioxaphospha cyclooctadiene (2b) were prepared by the reactions of high hindered 2,2'-diphenol methane (1) with dichlorophenylphosphine and phosphorus oxychloride, respectively. Stereochemistry of 2a and 2b and the reaction of 2a with benzil were studied. All prepared compounds have been confirmed by IR, 1HNMR, 31PNMR, MS and elemental analysis.
