Oxazdidone


The data provided at the beginning of this chapter show that zinc has a melting point and boiling point much lower than the preceding transition metals. This allows zinc to be melted or distilled without difficulty, and distillation may be used to purify zinc from less volatile metals. The low boiling point is an indication of weak metallic bonding, which in turn indicates that the filled 2>d electron levels are not extensively involved in forming zinc-zinc bonds in the metal. Moreover, zinc in its chemical behaviour shows few characteristics of a transition element it exhibits only one oxidaton state, +2, in either ionic or covalent compounds, indicating the involvement only of the two outer, 4s electrons. Its compounds are commonly colourless, but it does show a somewhat greater tendency to form complexes than the analogous elements (Ca, Sr, Ba) of Group II.  [c.417]

Dimethylamino-/f-octane from /i-Octan-2-ol.  [c.224]

Octan-2-ol (A), sometimes called sec.octy alcohol, can be obtained, at a low price and of high purity, from technical sources. As a secondary alcohol, it can be readily oxidised by potassium dichromate-sulphuric acid to n-hexyl  [c.224]

Required n-Octan-2-ol (redistilled), 61 ml. (50 g.) sodium dichromate dihydrate, 37 5 g. hydroxylamine sulphate, 80 g. (or the hydrochloride, 68-5 g.) hydrated sodium acetate, 25 g. sodium, 38 g. 40% formalin solution, 50 ml. formic acid, 80 ml. ethanol, 250 ml.  [c.224]

The cyclic carbamate (oxazoIidin-2-one) 313 is formed by the reaction of phenyl isocyanate (312) with vinyloxirane[I92]. Nitrogen serves as a nucleophile and attacks the carbon vicinal to the oxygen exclusively. The thermodynamically less stable Z-isomer 315 was obtained as a major product (10 I) by the reaction of 2-methoxy-l-naphthyI isocyanate (314) with a vinyloxir-  [c.332]
