Abstract

The 1,2-addition of aryl- or heteroarylboronic acids to aldehydes in the presence of PdCl₂ and P(1-Nap)₃ affords carbinol derivatives in very good yields. The reaction tolerates nitro, cyano, acetamido, acetoxy, acetyl, carboxyl, trifluoromethyl, fluoro, and chloro groups and allows the conversion of aliphatic aldehydes and hindered substrates.
