The acyclic imidoselenium(II) dihalides ClSe[N( Bu)Se]nCl (8.23, n =1 8.24, n = 2) are obtained from the reaction SeCla with tert-butylamine in a 2 3 molar ratio in THF. There are no sulfur or tellurium analogues of this class of chalcogen-nitrogen halide. 

Two pieces of chemical evidence support the three-membered ring formulation. The bifunctional oxazirane prepared from glyoxal, tert-butylamine, and peracetic acid (6) can be obtained in two crystalline isomeric forms. According to the three-membered ring formula there should be two asymmetric carbon atoms which should allow the existence of meso and racemic forms. A partial optical resolution was carried out with 2-7i-propyl-3-methyl-3-isobutyloxazirane. Brucine was oxidized to the N-oxide with excess of the oxazirane. It was found that the unused oxazirane was optically active. 

Reduction with lithium aluminum hydride allows a differentiation from the isomeric nitrones. Whereas 2-tert-butyl-3-phenyloxazirane (9) gives benzylidene-tert-butylamine [Eq. (10)], reduction of the isomeric nitrone leads to iV-benzyl-xV-fert-butylbydroxylaminc [Eq. 

To a solution of 1-(2,3-epoxypropoxy)-2-(2-tetrahydrofurfuryloxy)benzene in methanol are added tert-butylamine and water, the mixture is allowed to stand at 25°-30°C for 72 hours, and then the methanol is distilled off. The residue is dissolved in toluene and the solution is extracted twice with 5% oxalic acid. The aqueous extract is dried over potassium carbonate and concentrated to give Bufetrol. 

A mixture of 0,75 g of 5-(2,3-epoxy)propoxy-3,4-dihydrocarbostyril, 1.0 g of tert-butylamine and 25 ml of ethanol was stirred at a temperature of from 50°C to 55°C for a period of 4 hours. Ethanol and unreacted tert-butylamine were distilled off under reduced pressure and the resulting residue was dissolved in acetone.

Preparation of w-Phenyl-tert-Butylamine 24 grams of the urea derivative obtained as indicated above, were well mixed with 96 grams of calcium hydroxide in a flask immersed in an air bath and provided with a dropping funnel the stem of which reached the bottom of the flask. The mixture was heated to 240°-260°C (inside temperature) for 7 hours during which time 86 cc of water was slowly added. The vapors were collected in a receiver cooled with ice. After extraction with ether and distillation, the product was obtained as a colorless liquid boiling from 80°-84 C at 9 mm according to U.S. Patent 2,590,079. 

Step A Preparation of 3-tert-Butylamino-2-Oxopropanoi — To an aqueous solution of tert-butylamine (1 mol) at ambient temperature, there is added slowly and with vigorous stirring 2 mols bromoacetol. The reaction mixture is allowed to stand at ambient temperature for about 5 hours whereupon it is made basic by the addition of sodium hydroxide.

Oxetanes are significantly less reactive with nucleophiles due to diminished ring strain. Under certain conditions, however, amines can open oxetanes to give amino alcohols. tert-Butylamine reacts with oxetanes in the presence of Yb(OTf)3 to give 3-hydroxy amines. Lithium tetrafluorohorate has also been used for this...
