Ge 4 Cl 4 [MCp(CO) 3 ] 4 (M = Cr, Mo, W): A Series of Transition Metal Substituted Four‐membered Cyclogermanes

Synthesis, Characterization and Study of Some N-Substituted Aryl-2- ({4-[(Substituted Aryl Carbamoyl) Methyl]-5-(Pyridin-4-yl)-4H-1, 2, 4-Triazol-3-yl} Sulfanyl) Acetamide

Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...

Transition metal-free one-pot synthesis of 2-substituted 3-carboxy-4-quinolone and chromone derivatives.

A novel one-pot synthesis of the 2-substituted 3-carboxy-4-quinolone/chromone derivatives from readily available 3-oxo-3-arylpropanoates and amides/acyl chlorides is reported, without any transition metal aid.

مطالعات نظری بر روی ماهیت پیوندهای C→E و E→M در کمپلکس های [NHC→E2H4→M(CO)5] (E=Ge, Sn, Pb, M=Cr, Mo, W)

در این پروژه مطالعات نظری بر روی  ساختار و ماهیت پیوندهای  C EوE M  در برخی از کمپلکس های N-هتروسیکلیک کاربن با فرمول عمومی   [NHC→E2H4→M(CO)5]; (E=Ge, Sn, Pb, M=Cr, Mo, W) در سطح تئوریM06/def2-TZVP  گزارش شده است. انرژی برهمکنش پیوندهای C E  و E M در کمپلکس های فوق  محاسبه و مقادیر حاصل نشان داد که انرژی برهمکنش پیوندهای C→E  و E→M  در حضور اتم M یکسان و با تغییر اتم E از Ge به سمت Pb کاهش می ...
