Reactions of esters of formic acid, HCOOR (R=C<SUB>2</SUB>H<SUB>5</SUB>, CH<SUB>2</SUB>C<SUB>6</SUB>H<SUB>5</SUB>), with Ni(0)-complexes (mixtures of bis(1,5-cyclooctadiene)nickel (Ni(cod)<SUB>2</SUB>) and tertiary phosphines (PR′<SUB>3</SUB>)) lead to decarbonylation of HCOOR to afford (Ni(CO)<I><SUB>n</SUB></I> (PR″<SUB>3</SUB>)<SUB>4−<I>n</I></SUB> and ROH. Vinyl formate gives a mixture of CH<SUB>3</SUB>CHO, Ni(CO)<I><SUB>n</SUB></I>(PR′<SUB>3</SUB>)<SUB>4−<I>n</I></SUB>, C<SUB>2</SUB>H<SUB>4</SUB>, and CO<SUB>2</SUB> on interaction with the Ni(0)-complexes. β-Lactones liberate CO<SUB>2</SUB> on treatment with the Ni(0)-complexes. Oxidative addition of the reactants to Ni involving cleavage of the C–O bond(s) accounts for the formation of the products.
