Highly crosslinked polymeric reagents: Highly crosslinked polymeric reagents. Polymer-supported phosphines and their use in the conversion of alcohols to chloroalkanes. Sherrington, D. C.; Craig, D. J.; Dagleish, J.; Domin, G.; Taylor, J.; Meehan, G. V. (Dep. Pure Appl. Chem., Univ. Strathclyde, Glasgow, Scot.). Eur. Polym. J., 13(2), 73-6 (English) 1977. CODEN: EUPJAG. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 23 Divinylbenzene-styrene-styryldiphenylphosphine copolymer (I) [39319-11-4] samples were prepd. by suspension polymn. with crosslink d. 15, 25, and 37%, and 3 other samples with crosslink d. 37% were prepd. in the presence of PhMe at PhMe-monomer ratios 0.5-2:1. In CCl4 alcs. were converted to chloroalkanes by I in yields which decreased with increase in crosslink d. and increased with increase in PhMe-monomer ratio. Results indicate that a degree of substrate selectivity is achieved by varying crosslink d. I, crosslink d. 15%, gave results similar to those of similar P-contg. polymers of crosslink d. 1-2%. A mechanism was given, involving reaction of 2 equiv of P with 1 equiv of alc., thus showing a degree of mobility of the crosslinked chains.
