Bromide promoted decompn. of tert-Bu bromide in the presence of triphenylphosphine gives, besides isobutene, hydrogen(triphenyl)phosphonium bromide. When heated to approx. 150 DegC in the presence of xylene, the latter salt liberates hydrogen bromide which ...
A compound of formula (I): (X)nRuLL1 where n is 1 or 2, preferably 2, and in which Ru is ruthenium; each X independently is selected from Cl, SCN, H2O, Br, I, CN and SeCN and L is a ligand of formulae (a) to (g) and L1 is selected from a ligand of formulae ...

This paper is concerned with reaction systems in which fuel production is achieved by illumination of aqueous solutions. Research interest in this field focuses on the photoredox reaction A + D [graphic omitted] A–+ D+ in which A and D are solutes of which ...
A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts. ...

Homogeneous stereoisomeric olefins of the general formula I (R1 and R2 = alkyl, R3 = H and(or) alkyl) were prepd. by reacting a phosphorus ylide (general formula Ar3P+:C-HR) and a carbonyl compd. R2COR3 with stoichiometric amt. of a strong base, followed b ...
Objective: Develop an algorithm to decompose streamflow electrical conductivity signal into its “harmonics”, i.e. into the specific contribution of different ion species. Level: BS, Masters Description: The electrical conductivity (EC) of ...
Complex of general formula I in which R1, R2 and R3, which may be identical or different, represent separately a linear or branched alkyl radical of 1 to 5 carbon atoms, or, together with the nitrogen atom to which they are attached, a heterocyclic ...
