Kinetic evaluation of the solvolysis of isobutyl chloro-and chlorothioformate esters

The specific rates of solvolysis of isobutyl chloroformate (1) are reported at 40.0 °C and those for isobutyl chlorothioformate (2) are reported at 25.0 °C, in a variety of pure and binary aqueous organic mixtures with wide ranging nucleophilicity and ionizing power. For 1, we also report the first-order rate constants determined at different temperatures in pure ethanol (EtOH), methanol (MeOH), 80% EtOH, and in both 97% and 70% 2,2,2- trifluoroethanol (TFE). The enthalpy ΔH≠ and entropy ΔS≠ of activation values obtained from Arrhenius plots for 1 in these five solvents are reported. The specific rates of solvolysis were analyzed using the extended Grunwald-Winstein equation. Results obtained from correlation analysis using this linear free energy relationship (LFER) reinforce our previous suggestion that side-by-side addition-elimination and ionization mechanisms operate, and the relative importance is dependent on the type of chloro-or chlorothioformate substrate and the solvent.

Method for synthesizing organic carbonate from carbon dioxide, alcohol and brominated alkane under mild conditions

The invention discloses a method for synthesizing organic carbonate from carbon dioxide, alcohol and brominated alkane under mild conditions, belonging to the field of chemical synthesis. According tothe method, carbon dioxide, alcohol and brominated alkane are used as raw materials, 1,8-diazabicycloundec-7-ene (DBU) is used as an activating agent, and acetonitrile is used as a solvent to preparethe organic carbonate. The target product, namely the organic carbonate with excellent yield can be obtained under optimized reaction conditions. The method is mild in reaction conditions, simple andconvenient to operate and high in yield, and is an excellent system for preparing the organic carbonate.

Deamination Reactions, 41. Reactions of Aliphatic Diazonium Ions and Carbocations with Ethers

Aliphatic diazonium ions and carbocations were generated by deacylation of appropriate nitrosoureas (1, 5, 9) in alcohol-ether mixtures or in 2-alkoxyethanols.Ethers were generally inferior to alcohols in capturing cationic intermediates.Formation of trialkyloxonium ions led to alkyl exchange or ring opening.The observed reactivity orders were n-butyl > isobutyl for the diazonium ions, allyl > sec-butyl > tert-butyl for the carbocations, methoxy > ethoxy and oxirane > oxetane > tetrahydrofuran for the ethers, indicating the predominance of steric effects.Neighboring group participation in 4-methoxy-1-butanediazonium ions (58) and 4,5-epoxy-1-pentanediazonium ions (74) was detectable but inefficient ( 20percent of cyclic oxonium ions).
