FTIR Basic Organic Functional Group Reference Chart (PDF) Functional groups are structural units within organic compounds defined by specific atom and bond arrangements. Infrared is a powerful identification tool for functional groups because of the similar absorption frequencies for those groups in di...
Functional groups .In organic chemistry, functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the ...

Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter solely the location of functional groups are far less explored...
The selective (and controllable) modification of complex molecules with disparate functional groups (for example, natural products) is a long-standing challenge that has been addressed using catalysts tuned to perform singular transformations (for exampl

These simple procedures allowed the preparation of key precursors for other type of reactions such as cross-coupling reactions in order to introduce functional groups with tunable properties [18–20]. Among the different substituents linked to the corrole core, a special attention has been devoted ...
Click chemistry is a concept in which modular synthesis is used to rapidly find new molecules with desirable properties1. Copper(i)-catalysed azide–alkyne cycloaddition (CuAAC) triazole annulation and sulfur(vi) fluoride exchange (SuFEx) catalysis are w
However, most MMP inhibitors are small organic molecules with active zinc-chelating groups, such as hydroxylamine49 or mercaptan50, which may cause cardiac fibrosis51. Meanwhile, the use of transgenic methods to knock out specific genes related to MMP expression causes long-term effects rather than...
