摘　　要：An efficient synthetic method for diarylmethylphosphonates is presented.A series of phosphonate derivatives with diverse functional groups can be accessed via a rhodium catalyzed cross-coupling reaction between a-diazo phosphonates and aryl boronic acids.Migratory insertion of rhodium carbene intermediates is postulated to be the critical step in this transformation.An efficient synthetic method for diarylmethylphosphonates is presented.A series of phosphonate derivatives with diverse functional groups can be accessed via a rhodium catalyzed cross-coupling reaction between a-diazo phosphonates and aryl boronic acids.Migratory insertion of rhodium carbene intermediates is postulated to be the critical step in this transformation.
