A new noncatenated metal-organic framework containing pendant alcohol functionalities was synthesized. The alcohols were then post-synthetically converted to either lithium or magnesium alkoxides, with the incorporated metals anchored far from nodes or carboxylate functionalities. The metal alkoxide sites can be obtained stoichiometrically while maintaining the permanent porosity and large surf...

The conformational analysis of five β-chloroand β-bromo-alkoxides had been done. The minima and the conformational transition states were determined. The anti conformer was found to be the most stable one. Its percentage is more than 99. α-Methylation increases the nuclophilicity of oxygen .Consequently, it enhances the rate of the ring closure. In contrast to βmethylation which retards the rat...

Conventional MOCVD techniques require molecules displaying volatility and constant vapor pressure. Metal oxide precursors, i.e., b-diketonates, or classical or functionalized metal alkoxides are mostly solids. The various approaches used to tailor volatility are discussed with barium derivatives as an example. The relationships between sublimation temperature and molecular weight suggest that v...

Making one out of two: Dimeric boraza-crown ethers bridge the gap between metallacrowns and aza-crown with a strikingly simple synthesis. Dioxazaborocanes react alkoxides to form corresponding anionic boronates, which combine dimers upon ring-opening reactions. The presence was proven in solid state solution by X-ray crystallography NMR spectroscopy, respectively. influence counterion on stabil...

The Cover Feature shows a concerted carbonyl hydroboration mechanism involving Mg−O, B−H, and C=O bonds. Homoleptic magnesium alkoxides catalyze ketone with turn-over frequency (TOF) reaching up to 59,400 h−1 exhibit exceptional functional group tolerance. This TOF is so far the best observed in main catalyst without involvement of metal hydride intermediate. newly proposed finds general applic...

We report here kinetic and isotopic evidence for the elementary steps involved in dimethyl ether (DME) homologation and for their role in the preferential synthesis of 2,2,3-trimethylbutane (triptane) and isobutane. Rates of methylation of alkenes and of hydrogen transfer, isomerization and b-scission reactions of the corresponding alkoxides formed along the homologation path to triptane were m...
