摘要

Abstract Experimental and theoretical studies were conducted to explore the Z-selectivities in the Homer-Wadsworth-Emmons (HWE) reaction employing several methyl diarylphosphonoacetates (3, 4, 5 and 6) and aldehydes. The Z-selectivity depended upon the reaction conditions such as the bases, reaction temperature, and the aromatic suhstituents on the phosphorus atoms but the almost phosphonoacetates used in the ...
