The synthesis of diaryl alkanes and tertiary organoboronates via Barluenga coupling at roomtemperature occurred via photoactivated conversion of aryl sulfonyl hydrazones to diazo compounds in the presence of soluble bases. The combination of arylsulfonyl hydrazone and a soluble base is necessary to provide a near-UV chromophore. Using aromatic hydrazones and aromaticboronicacids resulted in rapid
