✦ Synopsis

The ionic liquids n-butylpyridinium tetrafluoroborate [bupy]BF 4 and 1-n-butyl-3-methylimidazolium tetrafluoroborate [bmim]BF 4 have been used as solvents for the Rh(I) catalyzed phenylacetylene polymerization in the presence of triethylamine as co-catalyst, obtaining high yields of poly(phenylacetylene). The complexes used are (diene)Rh(acac) and [(diene)RhCl] 2 [diene: 1,5-cyclooctadiene or norbornadiene]. The (nbd)Rh(acac) complex in both ionic liquids can be recycled without significant loss in activity. Molecular weights in the range between 55,000 and 200,000 Da have been obtained by GPC.
