Oligomerization and polymerization of alkynes catalyzed by rhodium(I) pyrazolate complexes
摘要:
Three new Rh(l) derivatives containing the dcmpz ligand (Hdcmpz: 3,5-dicarbomethoxypyrazole) have been prepared and employed as catalysts or catalyst precursors in the cyclotrimerization of terminal and internal alkynes and in the polymerization of ethyne to polyacetylene.
