The electrochemical oxidation of anodes of selected Main Group or late transition metals (M) in non-aqueous solutions of diphenyl diselenide gives the corresponding M(SePh)n compounds in high yields (M = Zn, Cd, n = 2; M = Cu, Ag, Tl, n = 1; M = Sn, n = 4). The addition of either 1,10-phenanthroline or triphenylphosphine to the electrochemical cell yields adducts in the case of cadmium and copper. The 77Se nmr spectra have been recorded. Keywords: electrochemistry, synthesis, phenylselenates, 77Se nmr spectra.

High Yields

The diol system in the side-chain of ecdysteroids reacts with phenylboronic acid under formation of cyclic esters. Phenylboronates of ecdysteroids I - V were prepared. The regiospecific reaction course was confirmed by 1H NMR spectra of the products. The reaction conditions were studied for 20-hydroxyecdysone (I). The phenylboronate can be prepared in high yields even in aqueous solutions. The liberation of the ecdysteroid I from the corresponding phenylboronate VI was performed using various reagents - diols or carboxylic acids.

Sacrificial Anodes

Dialkyldithiocarbamate derivatives (R2NCS2)nM of a number of metals (M = Fe, Co, Ni, Cu, Ag, Zn, Cd, In, Tl) have been synthesised in good yield by electrochemical oxidation of appropriate sacrificial anodes in non-aqueous solutions of either the corresponding tetraalkylthiuram disulphide (R2NCS2)2 (R = Me, Et) or a mixture of carbon disulphide plus the secondary amine R2NH (R = Et, i-Pr; R2NH = piperidine). Similar experiments with solutions of (EtO)2P(S)SH (= HL) gave MLn•derivatives (M = Fe, Co, Ni, Cu, Ag, Au, Zn, Cd, Hg, Ga, In, Tl) while in the presence of HL + 1,10-phenanthroline, MLn•phen derivatives were obtained for M = V, Mn, Fe, Co, Zn, and Ga.
