A transition-metal-free difluoromethylenation of diazo compounds that proceeds under mild conditions has been developed and is based on the use of TMSCF2Br as the difluoromethylene source and tetrabutylammonium bromide (TBAB) as the promoter. T

2,2-Difluoro-1-tributylstannylethenyl p-toluenesulfonate (2) was reacted with aryl iodides in the presence of 10 mol % of Pd(PPh3)4 and 10 mol % of CuI in DMF at 80 °C for 10-20 h to give the cross-coupled products 3 in 35-97% yields. Further coupling reaction of 3 with arylstannanes in the presence of 5 mol % of Pd(PPh3)4 and 3 equiv of LiBr in DMF at 100 °C for 2-24 h afforded the desired products 5 in 25-78% yields.
