STUDY ON THE SYNTHESIS AND REACTIONS OF N EW PHOSPHOCINS

New bis[2'-t-butyl-4'-methyl-(d, g) benzo]-2-phenyl-1,3,2-dioxaphospha cyclo-octadiene (2a) and bis [2'-t-butyl-4'-methyl-(d, g) benzo]-2-hyd roxy-2-oxy-1,3,2-dioxaphospha cyclooctadiene (2b) were prepared by the reactions of high hindered 2,2'-diphenol methane (1) with dichlorophe nylphosphine and phosphorus oxychloride, respectively. Stereochemistry of 2a and 2b and the reaction of 2a with benzil were studied. All pre pared compounds have been confirmed by IR, H-1 NMR, P-31 NMR, MS and e lemental analysis.
