PhenoFluorMix: Practical chemoselective deoxyfluorination of phenols

A practical deoxyfluorination with novel deoxyfluorinating reagent PhenoFluorMix, a mixture of N,N’-1,3-bis(2,6-diisopropylphenyl)chloroimidazolium chloride and CsF, is presented. PhenoFluorMix overcomes the challenges associated with hydrolysis of PhenoFluor. PhenoFluorMix does not hydrolyze, is readily available on decagram scale, and is storable in air. In this paper, we demonstrate the practicality of the reagent and exhibit the deoxyfluorination of a variety of phenols and heterocycles.

Encapsulation of a [Dy(OH2)8]3+ cation: Magneto-optical and theoretical studies of a caged, emissive SMM

The first supramolecular cage formed by three benzo-15-crown-5 macrocycles encapsulating a [Dy(OH2)8]3+ guest cation is reported, with the Dy(iii) centre exhibiting local pseudo square antiprismatic D4d symmetry. The anisotropy barrier extracted from ac susceptibility studies, emission spectroscopy and ab initio calculations reveals that the second excited state Kramers doublet plays a key role in the magnetization dynamics due to the Ising character and near coparallel nature of the ground and first excited Kramers doublets.

Modified Crown Ether Catalysts. 2. Synthesis of Alkanoyl-, Aroyl-, alpha-Hydroxyalkyl- and Alkylbenzo and Alkylcyclohexano Crown Ethers

Improved procedures for the synthesis and purification of alkanoyl- and aroylbenzo crown ethers are reported.Several new alkanoyl- and alpha-hydroxyalkylbenzo crown ethers were prepared.Alkylbenzo crown ethers were prepared in high yield by the Raney nickel catalyzed hydrogen-transfer reductions of the corresponding acyl- or hydroxyalkylbenzo crown ether compounds.The reduction of the tosylhydrazones of acylbenzo crown ethers with sodium borohydride in acetic acid also yielded the corresponding alkyl derivate.Attempted reduction of the acyl- and alpha-hydroxyalkylbenzo crown ethers by catalytic hydrogenation over palladium catalysts was unsuccessful apparently due to strong binding of the crown ethers to the catalyst.Alkylcyclohexano crown ethers were prepared by catalytic hydrogenation of the aromatic rings of the corresponding alkylbenzo crown ethers.

Method for joint production of 3 – methyl – 1, 5 – pentanediol and C1 – C6 alkoxide method (by machine translation)

The present invention provides a production of 3 – methyl – 1, 5 – pentanediol and C1 – C6 alkoxide method, comprises the following steps: 1) the 3 – methyl – 3 – butene – 1 – ol and C1 – C6 acid esterification reaction, is contained and C1 – C6 acid – 3 – methyl – 3 – butene – 1 – alcohol ester of the esterification product; 2) in the step 1) with the esterification product containing CO and H2 The gas hydroformylation reaction; 3) in the step 2) of the hydrogenolysis reaction to the reaction product, to obtain 3 – methyl – 1, 5 – pentanediol and C1 – C6 alcohol. The invention firstly esterification re-hydroformylation, hydrogenation process route, to avoid 3 – methyl – 3 – butene – 1 – ol directly hydroformylation, it is beneficial to avoid direct hydroformylation reaction generated by the side reaction of the inevitable; at the same time, the use of the process of the invention can also be co line C1 – C6 alcohol (for example ethanol).

Core?Shell Crystals of Porous Organic Cages

The first examples of core?shell porous molecular crystals are described. The physical properties of the core?shell crystals, such as surface hydrophobicity, CO2 /CH4 selectivity, are controlled by the chemical composition of the shell. This shows that porous core?shell molecular crystals can exhibit synergistic properties that out-perform materials built from the individual, constituent molecules.

Highly enantioselective borane reduction of prochiral ketones catalyzed by C3-symmetric tripodal beta-hydroxy amides

The asymmetric borane reduction of prochiral ketones with a series of easily constructed chiral C3-symmetric tripodal tris(beta- hydroxyamide) ligands was investigated. The borane complex of chiral ligand 1,1?,?,-(1,3,5-benzenetricarbonyl)-tris[(2S)-alpha, alpha-diphenyl-2-pyrrolidinemethanol] (1h) was found to be an efficient catalyst in asymmetric borane reduction of prochiral ketones and excellent enantioselectivities were obtained with both electron-deficient and electron-rich prochiral ketones (up to 97% ee).
