Journal ArticleDOI
Radical Substitution in the Nickeladithiolene Ring in Bis(1-phenyl-1,2-ethenedithiolato)nickel(0)
TL;DR: Substitution of the 1-cyano-1-methylethyl group for hydrogen in the nickeladithiolene ring occurs in the reaction of bis(1-phenyl-1,2-ethenedithiolato)nickel(0) with 2,2‘-azobis(isobutyronitrile). A radical mechanism is evidenced by the inhibition of the substitution in the presence of the radical scavenger TEMPO as discussed by the authors.
Journal ArticleDOI
An “adduct” between CpRh(S2C2Z2) and ZCCZ (Z= COOCH3) as an intermediate in CpRhI-catalyzed synthesis of tetramethyl-2,3,4,5-thiophenetetracarboxylate from elemental sulfur and ZCCZ

TL;DR: In this article, a rhodiadithiolene complex, η5-cyclopentadienyl(1, 2-dicarbomethoxy-1,2-ethylenedithiolato-S,S)rhodium, was formed by the reaction of CpRh(COD) with elemental sulfur (S8) and ZCCZ (Z = COOCH3; DMAD = dimethyl acetylenedicarboxylate) reacts further with DMAD to form a 1 1 adduct between C
Journal ArticleDOI
Structure and electrochemical behavior of alkylidene-bridged metalladithiolene complexes (metals: cobalt and rhodium): bond cleavage of alkylidene moieties by electrochemical redox reactions
TL;DR: In this article, a series of alkylidene-bridged metalladithiolene complexes were analyzed by cyclic voltammetry and it was shown that both reduction and oxidation weaken the M-S-C and S-C bonds in the triangle ring.
Journal ArticleDOI
Formation and reaction of three-membered cobaltathiaziridine ring in (η5-cyclopentadienyl)(substituted imido-κN-thio-κS-ethene-2-thiolato-κS)cobalt(III). Ring opening and closure and transfer of imido group

TL;DR: In this paper, the reduction halfwave potential values of the imido-bridged complexes depend on the substituent of bridging moiety, and they showed that the reductant of the original complex is regenerated not by the first reduction, but by the second reduction according to CV and OTTLE measurements.
