Manganese and rhenium-catalyzed selective reduction of esters to aldehydes with hydrosilanes was written by Wei, Duo;Buhaibeh, Ruqaya;Canac, Yves;Sortais, Jean-Baptiste. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020.Electric Literature of C10H11FO2 This article mentions the following:
The selective reduction of esters RC(O)OR1 [R = (4-chlorophenyl)methyl, naphthalen-2-ylmethyl, nonyl, etc.; R1 = Me, Et] to aldehydes RC(O)H (I), via the formation of stable alkyl silyl acetals RCH(OSi(C2H5)3)OR1 (II), for the first time, was achieved with both manganese, -Mn2(CO)10– and rhenium -Re2(CO)10– catalysts in the presence of triethylsilane as reductant. These two methods provide a direct access to a large variety of aliphatic and aromatic alkyl silyl acetals II and to the corresponding aldehydes I upon hydrolysis. The reactions proceeded in excellent yields and high selectivity at room temperature under photo-irradiation conditions (LED, 365 nm, 40 W, 9 h). In the experiment, the researchers used many compounds, for example, Ethyl 2-(4-fluorophenyl)acetate (cas: 587-88-2Electric Literature of C10H11FO2).
Ethyl 2-(4-fluorophenyl)acetate (cas: 587-88-2) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Electric Literature of C10H11FO2
