A lithiomethyl trimethylammonium reagent as a methylene donor.

چکیده
Straightforward deprotonation of soluble tetramethylammonium salts with alkyllithium reagents gives lithiomethyl trimethylammonium reagents. Coordination of the Li cation is crucial to the stability of these 'N-C ylides'. These reagents were used to prepare epoxides, aziridines and allylic alcohols.

Cyclopropanation of styrenes and stilbenes using lithiomethyl trimethylammonium triflate as methylene donor.
Lithiomethyl trimethylammonium triflate, prepared from tetramethylammonium triflate, cyclopropanates several styrenes and stilbenes with electron-donating and selected electron-withdrawing substituents efficiently. Kinetic data support a stepwise nucleophilic addition-ring closure mechanism for this methylenation.
متن کاملOxidative coupling of thiols to disulfides in solution radiation with Trimethylammonium Fluorochromate(VI), [(CH3)3NH[CrO3F], on Silica Gel
A mild and efficient method for the oxidative coupling of thiols by trimethylammonium fluorochromate(TriMFC) in solution is reported. Trimethylammonium fluorochromate is efficient and new reagent, whichprepares easily and oxidizes thiols to the corresponding disulfides quickly. The reactions perform cleanly andcontrolled to stop at the disulfide stage without over-oxidation side products.

متن کاملSynthesis and electropolymerization of phosphorylcholine-containing pyrroles and their hemocompatible properties.
A series of N-substituted pyrroles having phosphorylcholine with different methylene chain lengths between pyrrole group and phosphorylcholine group were synthesized and their electropolymerizations were performed in aqueous solution. The methylene chains were trimethylene (n = 3), pentamethylene (n = 5), nonamethylene (n = 9), and undecamethylene (n = 11), for 3-(1-pyrrolyl)propyl-2-(trimethyl...
