PhenoFluor™ Solution for Convenient, One-step Deoxyfluorination
The functional-group-tolerant, one-step conversion of phenols to aryl fluorides is a highly desirable process. PhenoFluor™ solution, provides straightforward method to fluorinate alcohol and phenols without preactivation and regioselectively fluorinate highly functionalized late-stage intermediates.
XtalFluor-E® and XtalFluor-M®: Convenient, Crystalline Deoxofluorination Reagents
This is an article regarding XtalFluor-E® and XtalFluor-M®: Convenient, Crystalline Deoxofluorination Reagents.
The chiral auxiliaries TADDOLs (α,α,α,α-tetraaryl-1,3-dioxolane-4,5- dimethanols) developed by Seebach's group have found numerous applications in asymmetric synthesis ranging from utilization as stoichiometric chiral reagents or in Lewis acid mediated reactions, to roles in catalytic hydrogenation and stereoregular metathesis polymerization.
Acid Halogenation Reagents
Fluoroamidinium salts were an advance in acid halogenation. Compared to chlorides, acid fluorides have greater water stability and a lack of conversion to the corresponding oxazolones upon treatment with organic bases.
Fluoroalkylation: Expansion of Togni Reagents
The fluoroalkylation toolbox now includes Togni reagents, hypervalent iodine perfluoroalkylation reagents, fluoroalkyl bromides, silanes, carboxylates, and sulfonyl fluorides for late stage fluoroalkylation.
