D. Houalla et al., NEW BICYCLOPHOSPHORANIC MACROCYCLES .3. M IXED MACROCYCLES FROM DIACRYLIC DIESTERS AND DIAMIDES, Phosphorus, sulfur and silicon and the related elements, 90(1-4), 1994, pp. 131-142
The bis (bicyclophosphoranes) containing macrocycles 4, 6, 8 and 9 hav
e been obtained by a Michael reaction between the precursors bis (hydr
idobicyclophosphoranes) 1, 2, 3 and the diacrylic diesters a and b. Th
e reaction of N,N'-methylene bis acrylamide c with the precursors 2 an
d 3 afforded the similar macrocycles 10 and 11 which have not been iso
lated.
