Experimental study and simulation of kinetics of acetophenone hydrosilylation with diphenylsilane in the presence of rhodium complexes in a microreactor
摘要:
The hydrosilylation of acetophenone with diphenylsilane in a microreactor in the presence of complexes [Rh(cod)Cl](2) and [Rh(CO)(2)(mu-Cl)](2) and (R)-(-)-cis-mirtanyl- and (R)-(+)-bornylamine in situ was studied, the kinetics simulation of the process was performed, and the multicriteria optimization of the process was carried out. The influence of the micro-mixing effect on the reaction rate was revealed. Best results in the microreactor were obtained for the [Rh(cod)Cl](2)-BornylNH(2) catalytic system. It was established that the formation of 1-phenylethanol and related enol silyl ethers are simultaneous competing reactions.

Provided herein are compounds useful for binding to one or more histone deacetylase enzymes (HDACs). The present application further provides radiolabeled compounds useful as a radiotracer for position emission tomography imaging of HDAC. Methods for prepared unlabeled and labeled compounds, diagnostic methods, and methods of treating diseases associated HDAC are also provided.
A novel strategy to construct complex polycyclic nitrogen-containing heterocycles from aliphatic amines via picolinamide-assisted palladium-catalyzed C–H bond activation reaction was reported. The reaction exhibits broad substrate scope for the synthesis of various azabicyclic scaffolds, including azetidines and tropane-class alkaloids. Application of this method to naturally occurring (−)-cis-myrtanylamine
据报道,有一种新的策略可以通过吡啶甲酰胺辅助的钯催化的C–H键活化反应从脂肪族胺中构建复杂的多环含氮杂环。该反应显示出广泛的底物范围,可用于合成各种氮杂双环支架,包括氮杂环丁烷和托烷类生物碱。该方法在天然存在的(-)-顺式-二甲基乙胺中的应用,这是前所未有的碳-碳键活化,其中涉及的电子对引发了环钯片段的分子内“ S N 2样”置换。第三中心,描述。
