A. Dupraz et al., POLYALKYLATION OF PRIMARY POLYOLS BY 1,4-ADDITION TO TERT-BUTYL ACRYLATE AND ACRYLONITRILE, Tetrahedron letters, 37(8), 1996, pp. 1237-1240
The very hydrophilic primary polyols pentaerythritol (PE), 1,1,1-tris-
(hydroxymethyl)ethane and tris(hydroxymethyl)aminomethane (TRIS), cam
be polyetherified in satisfactory yield by 1,4-addition to tert-butyl
acrylate using phase-transfer catalysis. Polycyanoethylation of these
polyols can also be accomplished with acrylonitrile. Preliminary resul
ts of chelation between some polyether-acids with samarium (III) are p
resented.
