Phenyl thioxophosphane (1) - generated by thermal cycloreversion from 7 along with the dihydropyridazine 8 - is trapped by cycloaddition with the o-quinones 9a-f by formation of the dioxaphospholsulfides 10a-f.Solvolysis of 10a-c, e and f with methanol yields the phenol derivatives 12a-e (in the case of 10b the isomer 12b' is formed, too).This reaction is reversible (12a-c-->10a-c) and accompanied by formation of the isomers 13a-c.The phenanthrene quinone methanide 14 is also suitable for the trapping reaction of 1 (-->15-->17). - Keywords: Phenyl Thioxophosphane, o-Quinones, -Cycloaddition, 1,3,2-Benzodioxaphosphol-2-sulfides
