The hydroformylation of 1-hexene with 12 bar 1 : H2/CO in the presence catalytic system [Rh(acac)(CO)2]/PPh3 was successfully studied by real-time multinuclear high-resolution FlowNMR spectroscopy at 50 °C.

An overview of organometallic or coordination multinuclear titanium complexes published so far is given herein. The majority these compounds are supramolecular homonuclear complexes, which listed according to their nuclearity and usually synthesized through one-pot procedures; the others mostly early-late heteronuclear complexes. We have attempted outline a systematic classification architectur...

The hypothesis that substrate availability can alter contractile function in reperfused myocardium after global ischemia was investigated in this study. Isolated rabbit hearts were placed in a dual tuned C'PI13C) NMR probe with a 9.4-T magnet and perfused with the following substrates given individually or in combination: 10 mM glucose, 2 mM palmitate, and 2.5 mM [3-13C]pyruvate. Glucose was th...

Carotenes are naturally abundant unsaturated hydrocarbon pigments, and their fascinating physical and chemical properties have been studied intensively not only for better understanding of the roles in biological processes but also for the use in artificial chemical systems. However, their metal-binding ability has been virtually unexplored. Here we report that β-carotene has the ability to ass...

Abstract A new multistage synthesis of the N-borylated dipeptide B 12 -PheGlyOH has been proposed. The approach is based on reaction nucleophilic addition amino acid derivatives to [B H 11 NCCH 3 ] – anion. products each stage have characterized by multinuclear NMR spectroscopy, IR absorption and ESI mass spectrometry.
