Photochemical reactions of 2-(alkoxycarbonyl)-, 2-cyano-, and 2-(phenylthio)cycloalkanones in alcoholic solution. Formation of ω-substituted esters was written by Tokuda, Masao;Watanabe, Yasuyuki;Itoh, Mitsuomi. And the article was included in Bulletin of the Chemical Society of Japan in 1978.Related Products of 18891-13-9 The following contents are mentioned in the article:
Photochem. reaction of Et 2-oxo-1-cyclohexanecarboxylate (I) in MeOH gave Et Me heptanedioate, trans– and cis-Et 7-oxo-2-heptenoate, and Et 7-oxo-3-heptenoate in 25, 7, 8, and 21% yields, resp. Photochem. reactions of I in EtOH, iso-PrOH, tert-BuOH gave the corresponding ω-alkoxycarbonyl esters. Other 2-(alkoxycarbonyl)cyclopentanones and -cycloheptanones underwent similar reactions to give the corresponding ω-alkoxycarbonyl esters. Photochem. reactions of 2-cyanocyclohexanones in MeOH similarly gave ω-cyano esters and ω-formyl α,β-unsaturated nitriles. However, photochem. reactions of 2-(phenylthio)- and 2-(methylthio)cyclohexanones in MeOH did not give the corresponding ω-phenylthio or ω-methylthio carboxylic acid esters, products resulting from cleavage of a carbon-sulfur bond being obtained. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Related Products of 18891-13-9).
Ethyl methyl adipate (cas: 18891-13-9) 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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Related Products of 18891-13-9
