Stoichiometric metals banned: Nonsymmetrically disubstituted alkynes were converted into primary trisubstitutedallylicalcohols upon exposure to paraformaldehyde in the presence of nickel or ruthenium catalysts, which exhibit complementary regioselectivity and complete stereoselectivity in the absence of exogenous reducing agents (see scheme).
