alpha or beta-hydroxy propargylic alcohols undergo tandem C(sp)-C(sp(3)) bond cleavage via beta-alkynyl elimination and homocoupling of the resulted alkynyl species in the presence of Cu(OAc)(2)center dot H2O to produce the corresponding hydroxycarbonyl compounds and 1,3-butadiynes....
The solid state reactions of Cu(OAc)2.H2O with 1-phenyl-3-methyl-4-benzoylpyrazolone-5(HPMBP, keto form and enol form) have been studied at low heating temperature (<100℃). It is shown that keto form HPMBP must be isomerized to its enol form in the process of the solid state rea...
