reaction of alkylhalides with lanthanum metal have been shown. The reduction of alkyl iodide with 1/3 equiv of lanthanum metal efficiently proceeded to give the corresponding reductive dimerized products along with the formation of reduction and dehydroiodination products. In the case of alkyl bromides and chlorides, the reaction did not proceed under the same reaction conditions as that of alkyl iodides;

Arylmethaniminyl and alkyl radicals were generated from di-
and tri-methoxyphenyl aldoxime esters, by photolysis in the presence of
4-methoxyacetophenone, and were detected by EPR spectroscopy: good yields
of cyclised products were isolated from suitably unsaturated alkyl
substituents.
