Highly efficient method for the preparation of N-tert-butyl amides by reaction of nitriles with tertbutylacetateis described using boron trifluoride etherate in solvent free condition. Selective amidation ofbenzonitrile in the presence of acetonitrile was also achieved.

A convenient oxidative sulfenylation method for the formation of various sulfenyl amides has been reported. Arenesulfonyl hydrazine as a sulfur source in the presence of a manganese salt can activate the sp(3) C-H bond of N-methyl amides through a free-radical pathway using di-tert-butyl peroxide (DTBP).

Condensation of the corresponding chlorides of some substituted pyrazine-2-carboxylic acids (pyrazine-2-carboxylic acid, 6-chloropyrazine-2-carboxylic acid, 5-tert-butylpyrazine-2-carboxylic acid or 5-tert-butyl-6-chloropyrazine-2-carboxylic acid) with various ring-substituted aminothiazoles or anilines yielded a series of amides. The syntheses, analytical and spectroscopic data of thirty newly...

The asymmetric unit of the title compound [Mn(NCS)(2)(C(9)H(13)N)(4)] consists of one Mn(II) cation located on a center of inversion, one thio-cyanato anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio. The Mn(II) cation is coordinate...

The asymmetric unit of the title compound, [Cd(NCS)(2)(C(9)H(13)N)(4)], consists of one Cd(II) cation located on a centre of inversion, one thio-cyanate anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.25:0.75 ratio and was refined using a split ...

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...

Silica chloride converted benzyl or tert-butyl esters to the corresponding acid chlorides and alkyl chlorides. It also converted benzyl or tert-butyl phenyl ethers to the corresponding allcyl chlorides and phenol

A simple, efficient, and cost-effective procedure for the N-tert-butoxycarbonylation and N-formylation of amines (primary, secondary) respectively, with di-tert-butyl dicarbonate and 85% aqueous formic acid under solvent-free condition using B(OSO3H)3/SiO2 (SBSA) as a heterogeneous and recyclable catalyst has been developed. We demonstrated that the resulting catalyst is applicable to various a...
