Gold-complexes catalyzed oxidative α-cyanation of tertiary amines.
Oxidative α-cyanation of tertiary amines is catalyzed by gold complexes with trimethylsilyl cyanide to afford the corresponding α-aminonitriles in the presence of tert-butyl hydroperoxide in good to excellent yields under acid-free conditions at room temperature.
متن کاملTHE DEALKYLATION OF TERTIARY AMINES WITH THIOPHOSGENE AND 1-CHLOROETHYL CHLOROTHIONOFORMATE
Thiophosgene and 1-chloroethyl chlorothionoformate react readily with tertiary amines, and give the dialkylamine hydrochloride after hydrolysis of the initial product with water. Benzyl and allyl groups are cleaved in preference to methyl and other alkyl groups. The rection with the isoquinoline alkaloid narcotine occurs particularly easily.

متن کاملGold(I) Complexes of Secondary and Tertiary Amines. Crystal Structure of Triphenylphosphineaurio(I)quinuclidinium Tetrafluoroborate
The secondary amine piperidine and the tertiary amine quinuclidine (l-azabicyclo[2.2.2]octane) were reacted in THF with one equivalent of triphenylphosphinegold(I) tetrafluoro borate, [Ph3PAu]+ BF4“, to give the monoaurated ammonium salts of formula [R„NHp_„)AuPPh3]+ BF4~ (n = 2, 3). The compounds were obtained as crystalline solids in good yields, and were characterized by IR and NM R spectro...
متن کاملTrapping of a Ruthenium-Butatrienylidene Intermediate by Tertiary Amines. 2-Ammoniobutenynyl Complexes†
2-Ammoniobutenynyl Ru-complexes trans-[Cl(dppm)2Ru-CtC-C(NR2R′)dCH2]PF6 (3ag) have been prepared in a one-pot procedure from cis-[RuCl2(dppm)2], excess butadiyne, and various tertairy amines, whereas 4-(dimethylamino)pyridine binds to the unsaturated carbon ligand via the pyridine nitrogen to give 3h. These results may be rationalized by envoking the butatrienylidene complex trans-[Cl(dppm)2Rud...
