Munoz, A.,Barrigues, B.,Koenig, M.
, p. 2467 - 2482 (2007/10/02)
Spirophosphoranes with a P-OH bond have been prepared as free acid (compound 5c, triethylammonium salts (compounds 2c-6c), or adducts 1/1 with DMF (compounds 5c and 6c).The ionic feature of triethylammonium salts of compounds 1c-6c, shows that these spiro
