The research focuses on the synthesis of N-arylsulfonyl nitroacetamides through a novel route involving the reaction of N-arylsulfonyl carbonimidodithioic acid dimethyl esters with nitroalkanes to generate I-alkylthio-I-aryl sulfonamido-2-nitroethylenes, which are then hydrolyzed to the desired nitroacetamides. Key chemicals involved in the research include N-arylsulfonyl carbonimidodithioic acid dimethyl esters (I), nitroalkanes such as nitromethane and nitroethane, anhydrous potassium carbonate, and mercuric chloride for the hydrolysis step. The study also investigates the solvent-dependent tautomerism observed in the nitroenamines 2a-d, noting that these compounds exhibit different tautomeric forms depending on the solvent used, with the imine form predominating in non-polar solvents and the enamine form in polar solvents. This work provides a general synthetic route for a wide variety of substituted nitroacetamides, which are otherwise challenging to synthesize using conventional methods.

The research focuses on the synthesis and complexation behavior of 1,2-bis(chloromercury)ferrocene (3), a redox-active bidentate Lewis acid. The study introduces a new rational synthesis of 1,2-bis(trimethylstannyl)ferrocene (2), which is converted to 1,2-bis(chloromercury)ferrocene (3) with high yield. Key chemicals involved in the synthesis include p-tolylsulfinylferrocene, tert-butyllithium, trimethyltin chloride, and mercuric chloride. The complexation behavior of 3 with DMSO and chloride anions was explored, yielding complexes that were characterized by X-ray crystallography. The study reveals different binding modes and supramolecular structures influenced by counterions, highlighting the potential of 3 as a versatile precursor for other bidentate Lewis acids and its applications in supramolecular chemistry.

The study explores the preparation of vinylmercuric halides through the preferential cleavage of the vinyl group from alkylvinyltin compounds using mercuric chloride, bromide, or iodide. The chemicals involved include n-butyldivinyltin, mercuric bromide, di-n-butyldivinyltin, and mercuric chloride. The vinyl group's lability in organotin compounds is utilized to synthesize vinylmercuric halides, which are reported for the first time. The reaction is conducted using a Soxhlet extraction apparatus, which moderates the vigorous reaction and requires only small quantities of solvent. The study lists the melting points and analytical data of the three vinylmercuric halides obtained and mentions that further work utilizing these compounds in other organometallic syntheses is in progress.

The study investigates the reactions of ethynylvinyl ethers and thioethynylvinyl ethers with carbonyl compounds, focusing on their interactions with the ethyl ester of orthoformic acid and formaldehyde. Ethynylvinyl ethers and thioethynylvinyl ethers serve as the primary reactants, while the ethyl ester of orthoformic acid and formaldehyde act as key reagents. The organo-magnesium complex is utilized to facilitate the reactions, leading to the formation of various etheracetals and thioetheracetals containing a pentene-l-yne-3 chain of carbon atoms. These products are of significant interest due to their potential for further synthesis and the expansion of carbon chains. Additionally, the study explores the hydrogenation of these compounds and their decomposition using an alcoholic solution of mercuric chloride, providing insights into the stability and reactivity of the synthesized compounds.
