Decarboxylative Transformations Facilitated via Intermolecular Halogen Transposition using gem-Bromonitroalkanes
… photoredox-catalyzed elimination and cross-coupling methodologies were developed via merger of decarboxylation with intermolecular halogen transposition using gem-bromonitroalkanes. A systematic investigation of this novel synthetic framework enabled mild, green, and efficient conversion of …

Nickel-catalyzed cross-couplings of unactivated secondary and tertiary alkyl halides and photoinduced copper-mediated asymmetric C-N cross-couplings
… development of two nickel-catalyzed Suzuki cross-coupling methodologies that employ alkyl halides as electrophiles. In Section 1.1, asymmetric [gamma]-alkylation relative to a carbonyl group is achieved via the stereoconvergent cross-coupling of racemic secondary [gamma]-chloroamides with primary …

Development of N-Heterocyclic Carbenes as Organic Catalysts and Efficient Ligands in Palladium Mediated Transformations
… phosphines in transition metal catalyzed cross-coupling chemistry. The advantages of NHCs over phosphines include ease of handling, minimal toxicity, stability and powerful electron donating properties. Improvement of catalytic processes has become increasingly relevant in light of prospective …

TRANSITION METAL CATALYZED CROSS-COUPLINGS OF ALKYL SULFONE ELECTROPHILES
… While their use as Csp2 electrophiles in cross-coupling dates to the early 1970’s, their potential as competent Csp3 electrophiles has not been recognized until recently. Our group has made significant contributions to the development of new cross-coupling methodologies utilizing alkyl sulfones …

Design, analysis and validation of electrode-less plasma generator
The current work investigates a method for generating plasmas without damaging electrodes. The primary objective is the creation of an electrode-less potential region (virtual cathode) through the use of electron emission and active feed of radio frequency (RF) signal. The reason for pursuing this …
