DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 38 Several reactions involving crosslinked polymers, a solid, and a liq. phase were investigated. Wittig reactions between crosslinked polymers contg. phosphonium salt residues, solid K2CO3, and aldehydes in THF proceeded satisfactorily, even in the absence of a phase-transfer catalyst. The oxidn. of 2-phenyl-1,2-propanediol [4217-66-7] in CH2Cl2 by solid NaIO4 (but not KIO4) was catalyzed by the periodate form of an anion exchange resin. The reaction of 1-bromooctane [111-83-1] in benzene, THF, or MeCN with KCN or NaCN and of benzyl bromide [100-39-0] in THF or MeCN with KOAc or NaOAc were catalyzed only slightly, if at all, by the cyanide or acetate forms of an anion exchange resin. Crosslinked polymers contg. crown ether residues catalyzed the reaction of 1-bromooctane in PhMe with NaI. It was not clear how the crosslinked polymers and solid reagents managed to react with each other, but possible mechanisms were discussed. The importance of carrying out control reactions in such studies was stressed. .
