The trifluorophosphoranes TrtRPF 3 (R = tert.-Bu (1), Ph (2), NEt 2 (3)) were obtained by the oxidative addition of TrtF (Trt = triphenylmethyl) to the difluorophosphines RPF 2 . At room temperature only 1 exhibited dynamic behaviour in solution, but at Β±5 Β°C the pseudorotation was slow enough to pe
