摘要

Abstract Rhodium (I) dicarbonyl complexes 1–4 containing chelating N-donor ligands bis (pyrazolyl) methane (bpm), bis (imidazolyl) methane (bim), tris (pyrazolyl) toluidine (tpt) or tris (imidazolyl) methanol (tim) were investigated as catalysts for the hydroalkoxylation of alkynyl benzoic acids (5a–g). The regioselectivity of the reaction was shown to be highly dependent on the nature of the terminal alkyne substituent (R) of the alkynol substrate. It ...
