Lactams from cyclic amines. A mixture of iodosobenzene and water stirred for 15 min, the slurry cooled to 0°, treated in one portion with pyrrolidine, stirred at 9" for 1 h, then at room temp, until a clear soln. was obtained (4-5 h) - 2-pyrrolidinone. Y 49%. F.e. inch 3,4-dihydroisocarbostyrils and 2-piperidones, also nitriles from prim, amines, and cyclic ketones from cycloalkylamines, s. R.M. Moriarty et al., Tetrahedron Letters 29, 6913-6 (1988) cyclic azomethines in methylene chloride cf. ibid. 6917-20. [Pg.331]

A soln. of p-methylbenzyl alcohol in ethyl acetate stirred 0.5 hr. at room temp, with excess aq. 10%-NaCl (commercial bleach) in the presence of ca. 5% tetrabutylammonium hydrogen sulfate as phase transfer catalyst p-tolualdehyde. Y ca. 100%. - Similarly Cyclohexylamine, after hydrolysis of the intermediate N-chlorimine with dil. mineral acid -> cyclohexanone. Y 98%. F. e., also nitriles from prim, amines, and limitations, s.

Bei der Reduktion von Aldehyden und Ketonen werden neben den Alkoholen auch Di- und Polysulfane er-halten (s. S. 276), mit aromatischen Nitrilen im UberschuB5, mit Oxiranen (S. 422) und mit Thiiranen (S. 449) werden Thioamide, Dihydroxy-disulfane oder Polysulfane gebildet. Mit Thiolen entstehen Borsaure-trithioester, die mit Aldehyden und Ketonen Thioacetale ergeben6. Prim. Nitro-alkane Iiefern Nitrile, sek. Ketone und Oxime (S. 472), Nitro-aromaten die entspreehenden Amine (S. 478). Oxime konnen selektiv zu Hydroxylaminen Oder weiter zu Aminen reduziert werden (S. 375). [Pg.22]

Class 2 Molecules with active H-atoms and electronegative atoms with pairs of free electrons (0, N, F) Alcohols, acids, phenols, prim, and sek. amines, oximes, nitro compoimds and nitriles with a-H-atoms like hydrazine, NH3, HF, HCN, etc. [Pg.47]

Alcohols from oxo compds. 20 eqs. NaBH4 added to a soln. of 5 eqs. ZrC in THF at room temp, under N2, a soln. of 4 eqs. acetophenone in the same solvent added, and the mixture stirred at room temp, for 5 h - 1-phenylethanol. Y 96%. ZrCl4 is inexpensive, easy to use, and does not affect ar. nitro compds. and bromides. F.e., also reduction of carboxylic acids, esters and halides to prim, alcohols, and amides, oximes, alkoximes, nitriles, and imines to amines, s. S. Itsuno et al.. Synthesis 1988, 995-6. [Pg.24]
