✦ Synopsis


This paper presents the synthesis and characterization by mass spectrometry and NMR spectroscopy of [2-13 C]-and [3-13 C]ubiquinone-0 and of [5-13 C]-and [6-13 C]ubiquinone-10. A scheme based on the synthetic approach to [5-13 C]ubiquinone-10 has been worked out for the synthesis of ubiquinones 13 C-labeled at any individual position and at every combination of positions in the quinone ring. The [5-13 C]and [6-13 C]ubiquinone-10 isotopomers were incorporated

Three selectively labeled propynes were prepared either with deuterium or carbon-13 at position 3 and doubly labeled with carbon-13 at positions 1 and 2 by an alkylation reaction from the corresponding labeled or unlabeled monolithio acetylides and dimethylsulfates.

The reaction of 2,6-diarylidenecyclohexanones with hydrazine hydrate in glacial acetic acid resulted in the formation of diastereomers of (E)-2-acetyl-3-aryl-7-arylidene-3,3a,4,5,6,7-hexahydroindazoles. The relative conÐgurations of these diastereomers were unambiguously assigned using 1H and 13C NM

The novel thioantimonate(III) [Fe(C 4 H 13 N 3 ) 2 ]Sb 6 S 10 • 0.5 H 2 O was synthesised under mild hydrothermal conditions by allowing elemental Fe, Sb, and S to react in a 50% diethylenetriamine (dien) solution. The compound crystallises in the monoclinic space group C2/c with a = 33.789(3), b =
