Accordingly, iterative use of commercially available vinylmagnesium bromide (2), 47% hydrobromic acid, and
methyl acetoacetate (3) enables us to prepare 1 from all commercially available 2-hexanone (4, Fig.
An equimolar mixture of hydrazine hydrate (1) (1 mmol),
methyl acetoacetate (2) (1 mmol), 4-methoxy benzaldehyde (3) (1 mmol), ethylcyano acetate (4) (1 mmol), and ZnO nanoparticles (9 mol%) in water (2 mL) was refluxed for 40 min.
Ethyl acetoacetate,
methyl acetoacetate, dimethyl acetoacetamide, monomethyl acetoacetamide, and acetoacetanilide are low color copromoters for room-temperature cure of unsaturated polyesters.
Offers ethyl acetoacetate,
methyl acetoacetate, dimethyl acetoacetamide, mono-methyl acetoacetamide, and acetoacetanilide for use as low-color copromoters for room-temperature cure of unsaturated polyesters.
