One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 7492-70-8, Name is Butyl Butyryllactate, formurla is C11H20O4. In a document, author is Yang, Ling, introducing its new discovery. Quality Control of Butyl Butyryllactate.
Photochemical Radical C-H Halogenation of Benzyl N-Methyliminodiacetyl (MIDA) Boronates: Synthesis of alpha-Functionalized Alkyl Boronates
alpha-Haloboronates are useful organic synthons that can be converted to a diverse array of alpha-substituted alkyl borons. Methods to alpha-haloboronates are limiting and often suffer from harsh reaction conditions. Reported herein is a photochemical radical C-H halogenation of benzyl N-methyliminodiacetyl (MIDA) boronates. Fluorination, chlorination, and bromination reactions were effective by using this protocol. Upon reaction with different nucleophiles, the C-Br bond in the brominated product could be readily transformed to a series of C-C, C-O, C-N, C-S, C-P, and C-I bonds, some of which are difficult to forge with alpha-halo sp(2)-B boronate esters. An activation effect of B(MIDA) moiety was found.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 7492-70-8 help many people in the next few years. Quality Control of Butyl Butyryllactate.
