Reactions of Group IV organometallic compounds. Part XXVI. Insertion reactions of isocyanates and isothiocyanates to N-trimethylsilyl-(diphenylmethylene)amine and subsequent [4 + 2] cycloadditions of isocyanates with their adducts

Journal of the Chemical Society, Perkin Transactions 1, 1972
N-Trimethylsilyl(diphenylmethylene)amine reacted with 1 mol. equiv. of methyl, phenyl, or benzoyl isocyanate, and with the corresponding isothiocyanates, by the selective cleavage of the Si–N bond. The n.m.r. spectra of the 1:1 insertion product (III)–(VIII) showed the non-equivalency of trimethylsilyl proton signals at low temperature.

Electrophilically trapping water for preventing polymerization of cyclic ether towards low-temperature Li metal battery.

Angewandte Chemie, 2023
Cyclic ether with low freezing point, such as 1,3-dioxolane (DOL), is promising solvent for low-temperature electrolytes, yet the practical implantation is severely limited since it easily polymerizes in the presence of lithium inorganic salts. The trace

Stereoselective Synthesis of 12-Tetrazolyl Substituted (E)-5H-Quinazolino[3,2-a]quinazolines via Sequential Ugi-Azide/Staudinger/aza-Wittig/Addition/Ag(I)-Catalyzed Cyclization.

Journal of Organic Chemistry, 2023
A new efficient and stereoselective synthesis of 12-tetrazolyl substituted (E)-5H-quinazolino[3,2-a]quinazolines via sequential Ugi-azide/Staudinger/aza-Wittig/addition/Ag(I)-catalyzed cyclization was developed.
