A new stable germaphosphene and some of its chemical properties

A new stable germaphosphene, the 2,2-dimesityl-1-(2,4,6-triisopropylphenyl)germaphosphene (1), has been made.It reacts quantitatively with benzaldehyde and α-phenyl-N-tert-butylnitrone to afford, by - and -cycloadditions, respectively, the corresponding four- and five-membered heterocycles 10 and 13.The conformations of these heterocycles are discussed.The reactions of 1 and the 2,2-dimesityl-1-(2,4,6-tri-tert-butylphenyl)germaphosphene (2) with these reagents are compared.

SYNTHESIS AND REACTIVITY OF NEW GERMA- AND STANNAPHOSPHENES

New stable compounds with a germanium (or a tin)-phosphorus double bond have been prepared respectively by a one step reaction between a lithiophosphide and a difluorogermane, or by dehydrofluorination of the corresponding fluorostannyl-phosphine with tert-butyllithium.Various types of cycloadditions (, and ) have been observed with aldehydes, nitrones and α-ethylenic aldehydes and ketones.
