The blend is partially crosslinked with a vinyl monomer when dissolved in an organic aprotic solvent and has a pH of 5.0 or lower. The first block copolymer is prepared by polycondensing a bis-hydroxyalkyl ether, such as dipropylene glycol, diethylene glycol, and the like, with propylene oxide. Next, the resulting propoxylated diol is reacted with ethylene oxide to produce the block copolymer. The second copolymer is prepared by polycondensing 2-amino-2-hydroxymethyl-1,3-propanediol, commonly known as TRIS, with...

Gopolymerization of 3-(hydroxymethyl)-3-methyloxetane (MeOx) with oxetane containing in position 3 the -[0GH2GH2]30CH3 substituent (MEMO) led to branched polymers with short oligo(ethylene oxide) chains. These materials were tested as potential solid polymer electrolytes. 

Polymeric fluorinated surfactants (1) have a fluorinated backbone or (2) contain perfluroalkyl groups, as pendant perfluoroalkyl groups attached directly or indirectly to the polymer backbone, or as one or two fluorinated end groups of the polymer. A perfluoroalkyl tail can be attached to poly(tris(hydroxymethyl)-acrylamidomethane or to a natural product, such as a sugar, polyol, and so forth [180]. A fluorinated group may be attached to a poly(oxyethylene) chain —CH2CH2O—, to an ethylene oxide-propylene oxide block polymer, or to an acrylic comonomer. 

This group has developed a new selective source of nucleophilic hydroxymethyl (CH2OH) radical by persulfate oxidation of ethylene glycol catalyzed by Ag(I) salts. This nucleophilic radical is selectively trapped by protonated N-heteroaromahc bases, providing a new general hydroxymethylation protocol (Equahon 14.12) [23]. 

Hydroxyketones are versatile intermediates in the synthesis of pharmaceutical intermediates and heterocyclic molecules. a-Aryl hydroxyketones have been prepared by reaction of aryl aldehydes with 1,4-dioxane followed by reduction with lithium aluminum hydride (LAH) and by the selective LAH reduction of a-silyloxy a,P-unsaturated esters." WissneC has shown that treatment of acid chlorides with tris(trimethylsilyloxy)ethylene affords alkyl and aryl hydroxymethyl ketones. 1-Hydroxy-3-phenyl-2-propanone (3) has been generated by the osmium-catalyzed oxidation of phenylpropene and by the palladium-catalyzed rearrangement of phenyl epoxy alcohoP both in 62% yield. 

Quinoxaline-2-carboxaldehyde has been converted into the 2-carboxylic acid by oxidation with potassium permanganate in acetone and reduced to the 2-hydroxymethyl compound by treatment with formalin and potassium hydroxide. It also undergoes other typical reactions of aromatic aldehydes such as benzoin formation on reaction with potassium cyanide - and condensation reactions with malonic acid and its diethyl ester and Schiff base formation. Acid-catalyzed reaction of quinoxaline-2-carboxaldehyde with ethylene glycol gives the cyclic acetal the diethylacetal has been prepared by reaction of 2-dibromomethylquinoxaline with sodium ethoxide. " An indirect preparation of the oxime 11 is achieved by treatment of 2-nitromethyl-quinoxaline (10) with diazomethane followed by thermolysis of the resulting nitronic ester.

Introduction of a hydroxymethyl group at the ethylene bridge of EDOT represents an alternative and practical approach for the functionalization of EDOT [79], After the introduction of functional groups was performed by Williamson alkylation or esterification reaction starting from 16 (Scheme 9.15), anodic oxidation led to the corresponding polymers. 

In the last decades, many protocols to promote the nucleophilic free-radical Minisci reaction have been developed. Stoichiometric amounts of cerium(IV) salts were used to afford the carbamoylation of heteroaromatic bases catalyzed by N-hydroxyphthalimide under anaerobic conditions [19]. At the same time, catalytic quantities of cobalt(ll) salts in the presence of oxygen were used together with N-hydroxyphthalimide to promote tiie acylation of bases [20]. Ethylene glycol in the presence of the oxidizing system made of Ag(l) and persulfate salts gave high yields of the corresponding hydroxymethylated bases [21]. Similarly, nucleophilic fluorinated radical intermediates allowed to insert perfluoroalkyl substituents onto heteroaromatic bases (Scheme 12, product 12) [22] and quinones (Scheme 12, product 13) [23].
