Abstract: The [3+2] reactions between epoxides and carbon dioxide proceeded effectively in the presence of bifunctional tetraarylphosphonium salt catalysts, affording the corresponding cyclic carbonates in high yields. The use of isocyanates instead of carbon dioxide was found to be efficient for the synthesis of oxazolidinones from epoxides. In addition, we have successfully developed a novel phosphonium ylide as a nucleophilic catalyst for selective acylation of primary alcohols.
