Zinc acetate amide

Vinyl ethers are prepared in a solution process at 150—200°C with alkaH metal hydroxide catalysts (32—34), although a vapor-phase process has been reported (35). A wide variety of vinyl ethers are produced commercially. Vinyl acetate has been manufactured from acetic acid and acetylene in a vapor-phase process using zinc acetate catalyst (36,37), but ethylene is the currently preferred raw material. Vinyl derivatives of amines, amides, and mercaptans can be made similarly. A/-Vinyl-2-pyrroHdinone is a commercially important monomer prepared by vinylation of 2-pyrroHdinone using a base catalyst. 

These treatments have been less widely investigated for PET chemical recycling. Ammonolysis consists of the reaction of PET with ammonia at temperatures between 70 and 180°C, usually under pressure and in the presence of ethylene glycol.65 The main product of the degradation is the TPA amide, which is obtained with a purity above 99% and in yields of around 90%. This reaction is also catalysed by zinc acetate, as in other PET chemolysis processes mentioned above.

Esters and amides of 2-(diethoxyphosphinoyl)-2-nitrosopropanoic acid (presumably in dimer form) are reduced by zinc-acetic acid to the corresponding 2-amino compound. ... 

Zinc-containing linseed oil-based poly(ester amide) resins with different loadings of zinc acetate were prepared by an in situ condensation polymerisation reaction between linseed oil fatty amide diol, phthaUc anhydride and zinc acetate (a divalent metal salt with different mole ratios) in the absence of any solvent (Fig. 5.3). Similarly, linseed oil based-poly(ester amide urethane)s with alumina, Zn and Cd were prepared in situ by the reaction of linseed oil-derived fatty amide diol, aluminium trihydroxide, divalent zinc/cadmium acetate and toluene-2,4/2,6-diisocyanate, using a minimal amount of solvent.Castor oil and soybean oil-based poly(ester amide) containing Cd and Zn were also prepared to obtain improved performance, including antimicrobial properties. ... 

PERA/Nano-ZnO bionanocomposite was synthesized in domestic microwave oven model LG MS 1927C operating at 230V- 50 Hz frequency. MicHERA (0.04 mole) and finely powdered divalent zinc acetate (1 wt%, 3 wt%, 5 wt% and 7 wt% of monomer) were taken in an Erlenmeyer flask and placed in a microwave oven for 2-3 min, thereafter finely powdered maleic anhydride (0.04 mole) was added in the same pot and kept again for 2-3 min under same conditions. The reaction was monitored by TLC and acid value. The synthesized bionanocomposites were translucent light yellow color liquids (98-100% yield), designated as PERA/nano ZnO-1, PERA/ nano ZnO-3, PERA/nano ZnO-5 and PERA/nano ZnO-7 (suffix indicates the % of divalent zinc acetate yield 100%).

The synthesis commences with a straightforward acylation of the primary amino group of L-cystine dimethyl ester (13) with 5-hexy-noyl chloride (14) to give amide 12 in 90% yield (see Scheme 3). The action of zinc dust in acetic acid on intermediate 12 accom-... 

Diiminatc zinc complexes are highly active catalysts in the copolymerization of epoxides and C02. Complexes that are catalytic are of the form ZnLX, where X is alkoxide, acetate, or bis(tri-methylsilyl)amide. Changing the ligand geometries of the complexes allows variation in the catalytic behavior and activity.941 The polymerization of lactide with diiminate zinc has also been studied.942... 

Acetals have been used in the presence of Lewis acids, particularly zinc chloride and ferric chloride, for the addition of phosphorus-halogen species to prepare 1-alkoxyphosphonic dichlorides and dialkyl 1-alkoxyphosphonates (from phosphorus trichloride and dialkyl phosphinous chlorides, respectively).143-145 It should be noted that good yields of these types of products have also been reported in the absence of catalysts.146 147 Other types of substrates have also been used in these types of processes. These include acylals,148 amidals,149 orthoformates,150 and orthoacetates.151... 

In summary, the direct insertion of zinc dust to organic halides is an excellent method for preparing a broad range of polyfunctional organozinc halides bearing various functional groups like an ester" , an ether, an acetate" , a ketone, cyano", halide" , N,N-bis(trimethylsilyl)amino °, primary and secondary amino, amide, phthalimide , sulfide, sulfoxide and sulfone , boronic ester , enone " or a phosphonate . An alternative method is based on transmetalation reactions.
