Ruthenium Hydride Catalyzed Silylvinylation of Alkynes
… for a highly selective intramolecular trans-silylvinylation of internal alkynes catalyzed by RuHCl(CO)(SIMes)(PPh3) is reported. The use of methyl vinyl ketone as an additive increased the efficiency of this transformation. This process was expanded upon using ethylene gas as an additive and …

Ruthenium-Catalyzed Transformations for the Synthesis of Conjugated Dienes
… presented. </p> <p> The development of the trans-silylvinylation of internal alkynes with acrylates and vinyl boronates to form conjugated dienes is discussed. This transformation was accomplished via a recently developed tandem silylative coupling using RuHCl(CO)(PCy3)2. The reaction …

Development of Improved Methodologies Toward the Formation of C-C and C-N Bonds
… studied: C-N bond formation, C-H borylation, and silylvinylation of alkynes. </p> <p>In Chapter 1, palladium-catalyzed amidation has been used to effectively form C-N bonds toward the synthesis of valuable imidazo[4,5-b]pyridines and imidazo[4,5-c]pyridines. The reaction conditions are tolerable …

Exploration of Transition Metal Catalyzed C−C and C−N Bond Formation to Access Synthetically Elusive Small Molecules
… the ruthenium hydride catalyzed intramolecular silylvinylation of alkynes under 80 psi of ethylene gas. This strategy affords a single diene isomer, is applicable to substrates with aryl and alkyl substitution at the propargyl and homopropargyl positions, and has been utilized in the synthesis …
