Metal-catalyzed decarbonylation of primary aldehydes at room temperature

The metal-catalyzed decarbonylation of primary aldehydes has been achieved at room temperature in THF solvent by utilization of catalytic amounts of Rh(PPh 3 ) 3 Cl (2, 5 mol %), in conjunction with stoichiometric amounts of diphenylphosphoryl azide (DPPA, 4)
