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 <2 + 2>- and <2 + 3>-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.
