Organosilicon compounds of the furan series. VI. Nitrogen- and sulfur-containing organosilicon derivatives of furan
Five new furfurylaminoorganylsilanes and furfurylaminoalkyltriorganylsilanes are synthesized by reacting furfurylamine with organylchlorosilanes, chloroalkyltriorganylsilanes, and triorganylhydrosilanes. Furfuraldoxime readily reacts with triorganylchlorosilanes in the presence of triethylamine to give O-triorganylsilyl substituted oximes. It is shown for the first time that in the presence of H2PtCl6 aldoximes undergo dehydrocondensation with triorganylsilanes, accompanied by reduction processes. Reaction of hexamethyldisilazane with pyromucamide gives the trimethylsilylamide. Pyromuconitrile and magnesium 3-(methyldiethylsilyl)propyl chloride gives 1-furyl-4-(methyldiethylsilyl)butanone-1. Reaction of organylchlorosilanes with furfurylmercaptan and sodium furfurylmercaptide permits synthesis of the first representatives of the sulfur-containing organosilicon derivatives of furan.
