When heated for several hours in refluxing solvent, allylzinc bromide forms a new organometallic compound with a bis-1,3-organozinc structure. This compound reacts with different compounds leading in most cases to attachment of the structural group:

Reductive cleavage of open chain and cyclic α-N,N-dialkylamino-substituted benzyl alkyl ethers 1a–f with a dispersion of Li metal and a catalytic amount of naphthalene in THF, allowed easy access to a wide array of α-N,N-dialkylamino-substituted benzyllithium derivatives. Reaction of these organometallics with various electrophiles afforded the expected products in satisfactory yields.
Certain m-dioxane-5-methylamines are useful analgesic agents and intermediate 2-substituted-1,3-propanediols are useful in the preparation of such compounds.
