A series of copper(I) amidinates of the general type [(R'NC(R)NR'')Cu](2) (R' and R'' = n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl; R = methyl, n-butyl) have been synthesized and characterized. These compounds are planar dimers, bridged by nearly linear N-Cu-N bonds. Their properties (volatility, low melting point, high thermal stability, and self-limited surface reactivity) ...

The molecule of the title compound, C(10)H(9)BrO(2), a doubly conjugated unsaturated ketone, is almost planar (r.m.s. deviation of the non-H atoms = 0.039 Å). In the crystal structure, two mol-ecules are linked across a centre of inversion to form a hydrogen-bonded dimer by way of two O-H⋯O links.

VT transition from the high-spin CoII to low-spin CoIII state was observed for complex (N-cyclo-hexyl-2-iminopyridine)(3,6-di-tert-butyl-o-benzosemiquinonato)(3,6-di-tert-butyl-catecholato)cobalt in both solid and liquid form. For first time we demonstrate a low-temperature nanosecond pump-probe XANES experiment revealing valence tautomeric solution of Co complex. Reversible induced under tempe...

The crystal structures of the salicylideneaniline derivatives N-salicylidene-4-tert-butyl-aniline (1), N-3,5-di-tert-butyl-salicylidene-3-methoxyaniline (2), N-3,5-di-tert-butyl-salicylidene-3-bromoaniline (3), N-3,5-di-tert-butyl-salicylidene-3-chloroaniline (4), N-3,5-di-tert-butyl-salicylidene-4-bromoaniline (5), N-3,5-di-tert-butyl-salicylidene-aniline (6), N-3,5-di-tert-butyl-salicylidene-...

Herein we present a mild, simple and environmentally friendly diazotization protocol of aromatic heteroaromatic anilines into stable diazonium salts that surpass previously reported procedures. The reaction proceeds with tert -butyl nitrite in the presence an equimolar amount or small excesses p -toluenesulfonic acid ethyl acetate, at room temperature. o -Phenylenediamines yield benzotriazolium...

Abstract To separate the azeotropic mixture n-butyl acetate and n-butanol by liquid–liquid extraction, three ionic liquids (ILs) 1-ethyl-3-methylimidazolium dihydrogen phosphate ([Emim]H2PO4), 1-butyl-3-methylimidazolium ([Bmim]H2PO4) 1-hexyl-3-methylimidazolium ([Hmim]H2PO4) were adopted as extractants. The equilibrium data for ternary mixtures (n-butyl acetate + n-butanol + [Emim]H2PO4/[Bmim]...

An efficient and straightforward method for one-pot synthesis of aryl azides from the corresponding amines, employing tributylstannyl azide as transfer reagent of N3 group is described. In this procedure diazotization of aryl amines occurs under mild conditions using tert-butyl nitrite (t-BuONO) and p-toluenesulfonic acid (TsOH). A variety of substituted aryl amines, with both electron-withdraw...

In the title compound, C(15)H(24)F(2)N(3)O(2)P, the phosphoryl and carbonyl groups adopt anti positions relative to each other. The P atom is in a tetra-hedral coordination environment and the environment of each N atom is essentially planar. In the crystal, adjacent mol-ecules are linked via N-H⋯O=P and N-H⋯O=C hydrogen bonds into an extended chain parallel to the a axis. The crystal studied w...
