New stable compounds with a germanium (or a tin)-phosphorus double bon
d have been prepared respectively by a one step reaction between a lit
hiophosphide and a difluorogermane, or by dehydrofluorination of the c
orresponding fluorostannylphosphine with tert-butyllithium. Various ty
pes of cycloadditions ([2+2], [2+3] and [2+4]) have been observed with
aldehydes, nitrones and alpha-ethylenic aldehydes and ketones.
