Methylene chloride aminomethylene

New syntheses of enamino-ketones by the ring-opening of isoxazoles with samarium di-iodide and with pentacarbonyliron, by the reaction of 2-alkyl-thiomethyl-3-alkylthioacrylophenones with amines, and by the intramolecular photoarylation of A -[2-(haloaryl)ethyl]-(3-enaminones, of enamino-diketones by the reaction of (3-chlorosulphonic acid chlorides with amines and by amino-methylenation of cyclic (3-dicarbonyl compounds, and of enamino-esters by aminomethylenation of esters and lactones and by the reaction of nitriles with magnesium enolates have been reported.
