Lattice solvent controlled photochromism of tripyridyl-triazine-based zinc bromide complexes

The development of new stimuli-responsive materials with controllable properties has been highly desirable in the past decade owing to their increasing application demand in various areas. In this work, two...

Activation of β-Diketones for CO2 Capturing and Utilization

Herein, we explore the use of β-diketones for CO2 fixation and utilization based on their dual Brønested acid/Lewis base character upon activation by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and zinc bromide (ZnBr2), respectively....

Oligo(amylene) from the reaction of fusel oil with zinc dihalide

Fusel oil was converted into the liquid hydrocarbon oligo(amylene) by zinc bromide catalysis.

First Zinc Bromide Promoted Annulative Domino Reactions between Enamines and Cyclic Morita–Baylis–Hillman Alcohols: Synthesis of N,O-Ketals

A new efficient ZnBr2-mediated annulative domino reaction between enamines and cyclic Morita–Baylis–Hillman (MBH) alcohols is disclosed. The process involves a tandem sequence (intermolecular conjugate addition of enamines to MBH alcohols and intramolecular nucleophilic addition of the hydroxyl moiety to the transiently generated iminium ion), affording the corresponding N,O-ketals diastereoselectively in good yields.
