Tnethylamine

Ultrasound promoted (17 kHz) decomposition of arenediazonium fluoro borates can also be effected m the presence of tnethylamine tnhydrofluoride in Freon 113 media For example, fluorobenzene can be obtained in 92-95% yield by this method [39] (equation 10)... [Pg.276]

The somfication technique does not work when (1) tnethylamine tnhydrofluoride IS eliminated or (2) when tnethylamine is used in place of tnethylamine tri hydrofluoride... [Pg.276]

The regio- and stereoselectivities of cycloadditions of trifluoroacetonitrile oxide, which is generated m situ by treatment of the tnfluoroacetohydroxamyl bromide etherate with tnethylamine in toluene (equation 31), have been determined in a senes of studies by Tanaka [55, 36, 37, 5 ]. The highly reactive nitnle oxide reacts regioselectively with a variety of activated terminal alkenes and alkynes (equations 32 and 33)... [Pg.808]

Tndecanedione, 47, 95 Tnethylamine, 46, 18 dehydrobromination of o-bromo-y-butyrolactone with, 46, 23 dehydrobromination of or.a -dibromo-dibenzyl ketone, 47, 62 dehydrochlormation of cyclohexane-carbonyl chloride, 47, 34 in synthesis of nicotinic anhydride with phosgene, 47, 90 Tnethyl orthoformate, condensation with N,N diphenylethylene-diaminc, 47,14... [Pg.139]

Tnethylamine was distilled from calcium hydride before use. [Pg.17]

Reactions of alcohols with sulfur tetrafluoride, because of decomposition and/or polymerization, usually do not give fluonnated products However, in the presence of a hydrogen fluoride scavenger like tnethylamine or pyridine, even such sensitive substrates as benzyhc alcohols [755], 2-phenylethanol, and 2-furylmethanol [757] can be fluonnated to give the expected fluoro derivatives (equation 73)... [Pg.233]
