Reactions of asymmetrically substituted o-quinones: 3,5-di-tert-butyl-1,2-benzoquinone with triphenyl-phosphine, -arsine, -stibine, their oxides and trialkyl phosphates

The entitled quinone 4 reacts with triphenylphosphine (3a) and triphenylarsine (3b) to give the cyclic products 12a and 12b, respectively. The same quinone reacts with triphenylstibine (3c) to yield the stibine-methylene 17. The reaction of oxides of 3a-c (5a-c) and trialkyl phosphates 6a-c with the same quinone 4 affords hydrogen bonded complexes 13a-c and o-quinol monophosphates 23a-c, respectively. In both cases compound 22 is the other product. Possible reaction mechanisms are proposed to explain the formation of the new adducts.
