摘要:The present invention relates to a synthesis method and synthesis reactor of high-selectivity 2-methylallyl chloride by taking isobutylene and chlorine gas as raw materials and performing a gas-phase chlorination reaction in a microchannel reactor with a cooling surface. The isobutylene and the chlorine gas are reacted in a T-shaped microchannel reactor, and the mixing speed is extremely fast. Meanwhile, the huge heat exchange area per unit volume can ensure that the reaction proceeds stably at a substantially constant temperature and has good controllability. Therefore, side reactions caused by excessive local temperature can be effectively suppressed, the reaction selectivity is high, and no coking phenomenon occurs.

摘要:Stable alpha -substituted boronic esters, e.g. for use in peptide synthesis, are prepared by reacting a substituted alkene of the formula: with a disubstituted borane of the formula: wherein: (i) R1 and R2 are each selected from various groups which are preferably not leaving groups; (ii) X is halogen or other leaving group; (iii) Y is H or lower alkyl; (iv) Q1 and Q2 are each selected from various groups which are preferably such that the borane is non-hydrolyzable, and particularly Q1 and Q2 together may represent a residue of a diol such as catechol or pinanediol.
