Y. Fort et al., NEW SELECTIVE SYNTHESES OF (METH)ACRYLIC MONOMERS - ISOCYANATES, CARBAMATES, UREAS AND ISOCYANURATES DERIVATIVES, Tetrahedron letters, 34(24), 1993, pp. 3857-3860
Condensation of sodium cyanate with haloalkyl(meth)acrylates under app
ropriate phase transfer catalytic conditions led to the selective form
ation of monomers containing isocyanate, carbamate, urea or isocyanura
te group. The selectivity of these new syntheses of such derivatives d
epends on the temperature and the water content of the reaction medium
