Synthesis of Zinc Dimethyldithiocarbamate by Reductive Disulfide Bond Cleavage of Tetramethylthiuram Disulfide in Presence of Zn2+
The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...
متن کاملNO2 bond cleavage by MoL3 complexes.
The cleavage of one N-O bond in NO2 by two equivalents of Mo(NRAr)3 has been shown to occur to form molybdenum oxide and nitrosyl complexes. The mechanism and electronic rearrangement of this reaction was investigated using density functional theory, using both a model Mo(NH2)3 system and the full [N((t)Bu)(3,5-dimethylphenyl)] experimental ligand. For the model ligand, several possible modes o...

متن کاملBy Cleavage of the Quadruple Bond in Mo , ( 0 , Ccf
Addition of an excess of t-butyl isocyanide to solid Mo2 (0, CCF3 )4 or MO?_ (0, CMe)4 gives (t-BuNC), Mo(Oz CCF3 )* or (t-BuNC), Mo(Oz CMe), , respectively. The quadruple bond in K4 MO* Cl8 or Cl4 MO, (n-Bus P)4 also can be cleaved by an excess of t-butyl isocyanide to yield (t-BuNC), MoCl, _ The anionic ligands can be exchanged with ammonium hexafluorophosphate in presence of excess t-BuNC to...
متن کاملOptimization of Nonenzymatic Microwave D-Cleavage and Disulfide Bond Cleavage
A nonenzymatic digestion technique allows proteins to be well suited for collision-induced dissociation tandem mass spectrometry. This method utilizes microwaves and Dithiothreitol (DTT) to selectively cleave at aspartic acid (D) and disulfide bonds. This microwave digestion technique is reproducible and produces peptides with a shortened sequence length. Insulin I is used in this study to opti...
