Provided herein are halogen-bonded complexes of Formula (I), wherein is a halogen bond; R1 is unsubstituted C1-3 fluoroalkyl; D is N(R2)3, ((R2)2N)2C=NR2, 0=S(R2)2, substituted or unsubstituted heterocyclyl, or substituted or unsubstituted heteroaryl, and wherein R2 and y are as defined herein. D----(I−−R1)y (I) Further provided are methods of preparing compounds of Formula (I), compositions, reagents, and kits comprising a compound of Formula (I), and methods for fluoroalkylating an organic compound using a compound of Formula (I).
The present invention provides 2,4-pyrimidinediamine compounds that inhibit the IgE and/or IgG receptor signaling cascades that lead to the release of chemical mediators, intermediates and methods of synthesizing the compounds and methods of using the compounds in a variety of contexts, including in the treatment and prevention of diseases characterized by, caused by or associated with the release of chemical mediators via degranulation and other processes effected by activation of the IgE and/or IgG receptor signaling cascades.

perfluoroalkyl motifs in the core structure, access to such analogues typically requires multi-step synthesis. Here, we report a mild, metal-free and operationally simple strategy for the direct perfluoroalkylation of uracils, cytosines and pyridinones through a visible-light induced pathway from perfluoroalkyl iodides. This photochemical transformation features synthetic simplicity, mild reaction
