Green Access to α-Haloalkyl and α-Halobenzyl Esters, Versatile Intermediates for the One-Pot Two-Step Synthesis of O, O ′-Diacyl Acetals Using Zinc-Based Ionic Liquid Catalyst
Fache, Fabienne,De Azpiazu, Ignasi,Pelotier, Béatrice,Piva, Olivier,Gozzi, Christel
, p. 2430 - 2434 (2019/05/27)
α-Haloalkyl and α-halobenzyl esters have been synthesized using a zinc-based ionic liquid catalyst, BMIZnCl 3. These esters can then react with acids without intermediate purification to obtain mixed O, O ′-diacyl acetals in a one-pot process.

Formyloxyacetoxyphenylmethane is a stable, water-tolerant, N-formylating reagent for primary and secondary amines that can be used under solvent-free conditions at room temperature to prepare a range of N-formamides, N-formylanilines, N-formyl-α-amino acids, N-formylpeptides, and an isocyanide.
Zn(OTf)2.6H2O catalysed acylation of aldehydes: Preparation of 1,1-diacetates and α-chloroalkyl esters
Su, Weike,Can, Jin
, p. 88 - 90 (2007/10/03)
1,1-Diacetates (acylals) and α-chloroalkyl esters were prepared from carbonyl compounds with acylating reagents in the presence of 5% mol hexaaqua zinc triflate [Zn(OTf)2.6H2O] with good yields under mild reaction conditions.
Electrophilic reactions of carboyl compounds and derivatives thereof: XIII preparation of bifunctional compounds from aldehydes and olefins by acylation under acidic catalysis
Luk'yanov,Koblik,Murad'yan
, p. 1593 - 1599 (2007/10/03)
The reactions of aldehydes and their O-acylated derivatives (α-chloroesters, acylals) with olefins and α-ethoxystyrene in the presence of SnCl4 and ZnCl2 were investigated. The reactions afforded various bifunctional derivatives: diols, hydroxyesters, chloroesters, 1,3-ketoalcohols.
Electrophilic Reactions of Carbonyl Compounds and Their Derivatives. IX. Reactions of 3,4-Dimethoxyphenylacetone with Heterocarbenium Ions To Form 2-Benzopyrylium Salts
Luk'yanov, S. M.
, p. 927 - 933 (2007/10/03)
Reactions of 3,4-dimethoxyphenylacetone with a series of carbonyl compounds and their derivatives (benzaldehyde, α-chloroesters, vinyl ethyl ether, and geminal chlorohydrocarbons) as sources of heterocarbenium ions under conditions of acid catalysis and also with heterocarbenium salts yield 2-benzopyrylium salts.
Reactions of Carbonyl Compounds with Tervalent Phosphorus Reagents. Part 11. A Re-examination of the Reaction of Benzaldehyde with Phosphorus Trichloride in the Presence of Acetic Anhydride
Michie, Jacqui K.,Miller, Allen J.
, p. 785 - 788 (2007/10/02)
The reaction of equimolar amounts of benzaldehyde, phosphorus trichloride, and acetic anhydride has been shown to involve successive formation of benzylidene diacetate (4) and α-chlorobehzyl acetate (5).By an Arbusov reaction, the latter is converted into the dimer (3), previously recognised as the precursor of α-hydroxybenzylphosphonic acid (1a), the known product of an aqueous work-up.A simple preparation of α-chlorobenzyl acetate (5) is described.
