Abstract:
A bottom-up ligand engineering strategy enables the construction of ionic metal-organic frameworks (iMOFs) with hierarchical porosity and abundant unsaturated Cu+ active sites via halogen anion coordination. These iMOFs exhibit exceptional water stability due to a unique Cu─Br stabilization mechanism. The defect-engineered frameworks demonstrate enhanced CO2 adsorption, efficient humid CO2 capture, and superior catalytic performance in CO2-epoxides coupling reaction, exhibiting size-selectivity correlated with their pore dimensions.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
