Matrix reactions of silicon difluoride as studied by infrared spectroscopy
Infrared matrix isolation spectroscopy has been employed to characterize monomeric silicon difluoride. Warm-up experiments show the development of several sets of new bands which indicate that this molecule polymerizes ...
Overhauser effect and NMR spectra of n-methyl methylenimine
Pure liquid samples of the simple but rather reactive species N-Methyl Methylenimine were studied at -60°C. The conventional NMR spectra and double resonance spectra were taken. The NMR constants and relative signs of three ...
Studies in terpene synthesis: a model investigation
In an attempt to find a feasible synthetic route to the C/D ring system in the terpene kaurene and the terpene alkaloids veatchine and garryine a model synthesis was undertaken. The benzal derivative (1) of 1-hydrindanone ...
The aglucone of sinigrin
The mechanism of the ascorbate-activated cleavage of sinigrin to mustard oil has been postulated as enzymatic hydrolysis of the thioglucoside to the aglucone, which undergoes spontaneous Lossen rearrangement to allyl ...
Phenolate radical coupling as a method of triterpene synthesis
The dienone [B] is a possible precursor for the synthesis of tetra- and pentacyclic triterpenes. In this investigation a synthesis of the dimeric phenol [A] and the conversion of [A] to [B] by a phenolate radical coupling ...
Rotational assignment and analysis of hyperfine structure of the microwave spectrum of chlorine dioxide
The microwave spectrum of chlorine dioxide has been studied and the frequencies of about 600 lines ranging from 8000 Mc to 55 000 Mc are tabulated. Several rotational transitions of C13502, C13702, and C1350 16018 have ...
