Interplay of Ionic Species in Salts of Homoleptic Quaternary Phosphonium Cations Bearing Linear Biphenyl Moieties

open access: yesCrystals, 2022
Quaternary phosphonium salts are popular candidates used in many chemical transformations and synthetic chemistry, notably in catalysis. We have examined the single crystals of two bulky phosphonium compounds, tetra([1,1′-biphenyl]-4-yl) phosphonium ...

Synthesis of stereodefined 1-aryl(heteroaryl) substituted 1,2-bis(2-bromopyridin-3-yl)ethenes by selective tandem Suzuki-Miyaura Cross-coupling reactions [PDF]

open access: yes, 2008
In this communication we show the preparation of stereodefined trisubstituted alkenes 2 can be achieved by sequential selective Suzuki-Miyaura reactions of 2-bromo-3-(2,2-dibromovinyl)pyridines.

Metal organic ionic framework based on the ionic metal complex and organic moiety as counter ion: A review

open access: yesHybrid Advances, 2022
Metal organic ionic frameworks (MOIFs) or inorgano-organic salts (IOSs) are the product of an ionic interaction between metal ionic complex and opposite organic ion in water, through ion exchange mechanism.

Synthesized Phosphonium Compounds Demonstrate Resistant Modulatory and Antibiofilm Formation Activities against Some Pathogenic Bacteria

open access: yesHeteroatom Chemistry, 2022
A library of six compounds with new hybrids in a single molecule triazole ring attached to the phosphonium salts was synthesized. Click chemistry was, however, used to synthesize the 1-, 2-, and 3-triazole intermediates as a tether for the hybrid ...
