Our research group has been involved in the area of synthetic inorganic chemistry toward designing of proficient strategies to achieve synthesis and characterization of unusual transition metal complexes, relevant structural-functional model systems for important enzyme active sites and discovering unusual reactivity with a goal to expand the scope of synthetic inorganic chemistry as well as bioinorganic chemistry.
The specific areas of interest include:
In particular, within the last 10 years we have achieved the following exciting results: (1) nonheme diiron(II) complexes which contain free thiols, (2) dinculear Co(II) complexes which contain only one terminal hydrosulfide, (3) nonheme mononitrosyl diiron complex with [FeII{FeNO}7] formulation which produces N2O upon reduction, (4) desulfurization of thiols, sulfides and thiophenes at room temperature, (5) nonheme diiron(II) and diiron(II, III) complexes with either one/two terminal/bridging hydrosulfide/s, (6) Co(II) and Fe(II) mediated consecutive cleavage of C-S and S-S bond in disulfides, (7) superreduction vs. semireduction mechanism for the conversion of NO to N2O mediated by two functional model complexes of FNORs, (8) isolation of the intermediate that leads to the transition metal mediated C-S bond clevage of thiolates in dinuclear Co(II)/Fe(II)/Ni(II) complexes, (9) syntheis of a unique nonheme monohydrosulfido dinitrosyldiiron complex with [HS{FeNO}7/{FeNO}7] formulation which produces N2O upon reduction, (10) two-electron redox reaction between coordinated thiolates and elemental sulfur to yield trisulfide (S32-) and pentasulfide (S52-) chain in binuclear Zn(II) complexes, (11) nitrite induced structural changes in binuclear Mn(II)-thiolate complexes, (12) Co(II) catalyzed hydrolysis of thiolates to alcohols and phenols, (13) redox convergent synthesis of a Co(III)-pentasulfido complex, (14) comparative hydrolysis and transfer reactivity of coordinated thiolate and selenolate in binuclear Zn(II) complexes.
