Programmed Negative Allostery with Guest-Selected Rotamers Control Anion-Anion Complexes of Stackable Macrocycles

A new rotamer-based strategy for negative allostery has been used to control host-host interactions and product yield upon anion complexation. Coassembly of anion dimers as guests inside two cyanostar macrocycles drives selection of one rotamer in which all ten steric groups get directed outward to destabilize triply stacked macrocycles. A large entropy penalty (ΔS) is quantified upon anion binding when the multiple dynamic rotamers collapse down to one.

Two Ligands Transfer from Ag to Pd: En Route to (SIPr)Pd(CF2H)(X) and Its Application in One-Pot C-H Borylation/Difluoromethylation

A process for the concurrent transfer of both the NHC ligand and the difluoromethyl group from [(SIPr)Ag(CF2H)] to PdX2 (X = Cl, OAc, and OPiv) for the preparation of [(SIPr)Pd(CF2H)X] complexes is described. These complexes were air-stable and easily underwent transmetalation with aryl pinacol boronate/reductive elimination to generate ArCF2H in high yields. Based on this discovery, the first one-pot C-H borylation and difluoromethylation process for the preparation of difluoromethylated (hetero)arenes was developed.

COMPOSITIONS AND METHODS FOR SELECTIVE SEPARATION OF HYDROCARBON ISOMERS

The present invention relates to novel metal-organic frameworks (MOFs) comprising tetratopic linkers with small pore apertures. The present invention further relates to methods of utilizing the MOFs of the invention to separate hydrocarbons through adsorptive processes. The present invention further relates to the discovery that Ca(H2tcpb) metal-organic framework (MOF) is capable of separating hydrocarbon isomers from one another through absorptive processes. In one aspect, the invention provides a method of separating C5-C8 hydrocarbon isomers, such that straight chain, mono-branched, and/or multi-branched isomers are each separated from one another. In certain embodiments, this separation is achieved by taking advantage of the temperature dependent adsorptive properties of Ca(H2tcpb) MOF.
