The reaction of (2,6-dimethylphenyl)diphenylmethylenephosphine (1) with tetrachloro-o-benzoquinone (2), 3,5-di-t-butyl-o-benzoquinone (3) and phenanthrenequinone (4) yielded the formal [2+4] cycloaddition products 5,14 and 19, respectively. In the given order, the rate of reaction and the formation of 1:2 adducts decreased. With 2 equivalents of the orthoquinones, the 1.2 adducts were the only products
