Synthesis of Isobutyl Aldehyde form Isobutyl Alcohol by the Catalytic Action of Copper-Magnesium-Oxide. II

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Isobutyl 3,5-dinitro­benzoate

In the structure of the title compound, C(11)H(12)N(2)O(6), the mol-ecules are stacked along the b axis without any π-π inter-actions. The stacked columns are linked together by non-classical inter-molecular C-H⋯O inter-actions,. In the molecule, the nitro groups make dihedral angles of 9.4 (5) and 10.3 (5)° with the benzene ring.

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Bis(N-isobutyl-N-propyl­dithio­carbamato-κ2 S,S′)zinc(II)

In the title compound, [Zn(C(8)H(16)NS(2))(2)], the Zn(II) atom is chelated by two S,S'-bidentate dithio-carbamate ions in a very distorted tetra-hedral geometry. The alkyl chains of the ligands are equally disordered over two sets of sites.
