Nucleophilic addition of triethylphosphite to 3-acetoxy-2-methylenealkanenitriles and methyl 3-acetoxy-2-methylenealkanoates provides (2E)-2-(diethoxyphosphorylmethyl)alk-2- enenitriles and methyl (2Z)-2-(diethoxy-phosphorylmethyl)alk-2-enoates respectively with good stereoselectivity.

Reaction of methyl 3-acetoxy-2-methylenealkanoates with the reducing agent, lithium aluminium hydride (LAH): ethanol (1 : 1), provides (2E)-2-methylalk-2-en-1-ols, whereas, reaction of 3-acetoxy-2-methylenealkanenitriles with the same reagent provides (2Z)-2-methylalk-2-enenitriles in high yields.
