Interaction of 2-diethylamino-5,5-dimethyl-1,3,2-dioxaphosphorinane with ortho-hydroxyphenols

The interaction of 2-diethylamido-5,5-dimethyl-1,3,2-dioxaphosphorinane with pyrocatechol, pyrogallol or pyrogallolarene results in the formation of 1,3-bis(5',5'-dimethyl-1',3',2'-dioxaphosphorinanoxy)-2,2-dimethylpropane; in the case of pyrogallolarene, the second product is a hemicarceplex whose calixarene cups are linked by two phosphoneopentylene bridges.

EVIDENCE IN SUPPORT OF TETRAOXASPIROPHOSPHORANE INTERMEDIATES WITH A SIX-MEMBERED RING AND A P-H BOND IN INTRAMOLECULAR TRANSESTERIFICATION REACTIONS

Preparation of tetraoxaspirophosphorane 5 via two possible routes, starting from the isomeric P(V) precursors 10 and 11 results in identical 31P NMR spectra indicative of various P(III) compounds.By analysis of the products and application of low-temperature 31P NMR techniques it is shown that the phosphorane 5 is involved as an intermediate in the intramolecular transesterification 10 ->//- 28 which rules out spirophosphorane 7.These results are rationalized on the basis of orientation effects and Pearson's HASB theory.
