Reactive aldehydes such as formaldehyde and α-chloro aldehydes can be successfully generated by treatment of readily available trioxane and α-chloro aldehyde trimers, respectively, with methylaluminum bis(2,6-diphenylphenoxide) (MAPH), and stabilized as their 1:1 coordination complexes with MAPH. The resulting CH 2 =O.MAPH complex reacts with a variety of olefins to furnish ene-reaction products with

New 3-azidoalka-1,3-dienylphosphonates were synthesized by a convenient and efficient method. These compounds are useful as intermediates in the preparation of 2-(diethoxyphosphoryl)-3-(3-phenyl-4,5-dihydroisoxazol-5-yl)-2H-azirines and 2-(diethoxyphosphoryl)-3-vinyl-2H-azirines.
