1Polycondensation of butenediol: synthesis of telechelic 2-butene-1,4-diol oligomers.

Kiesewetter MK1, Edward JA, Kim H, Waymouth RM.

J Am Chem Soc. 2011 Oct 19;133(41):16390-3. doi: 10.1021/ja207465h. Epub 2011 Sep 22.

The catalytic condensation of cis-2-butene-1,4-diol with CpRu(MQA)(C(3)H(5)) (Cp = cyclopentadienyl, MQA = 4-methoxyquinoline-2-carboxylate) generates poly(2-butenediol), an unsaturated telechelic polyether diol with molecular weights between 400 and 4600 g/mol. This Ru(IV) allyl catalyst enchains 2-butene-1,4-diol primarily as the linear trans-2-butenyl ether (92%) along with vinyl branches (8%). These telechelic oligomers are useful chain extenders and macromonomers, as demonstrated by their use in the synthesis of poly(lactide)-b-poly(butenediol)-b-poly(lactide) triblock copolymers.
