Easy Preparation of [Bis(trifluoroacetoxy)iodo]arenes from Iodoarenes, with Sodium Percarbonate as the Oxidant

One-Pot Preparations of Diaryliodonium Bromides from Iodoarenes and Arenes, with Sodium Perborate as the Oxidant

This paper reports a one-pot synthesis of the title bromides from both activated and deactivated iodoarenes which are first oxidized with anhydrous NaBO3·H2O/Ac2O/conc.H2SO4 liquid mixtures, then coupled in situ with benzene and activated arenes and, finally, precipitated out with a KBr solution; this method is easy, cheap, safe and fairly effective.

Syntheses of (Diacetoxyiodo)arenes or Iodylarenes from Iodoarenes with Sodium Periodate as the Oxidant

Easy, safe, and effective novel methods for preparing either (diacetoxyiodo)arenes, ArI(OAc)2, or iodylarenes, ArIO2, from the corresponding iodoarenes, ArI, using sodium periodate as the oxidant are presented in this paper. In order to obtain 2and 4iodylbenzoic acids, the respective sodium salts of 2and 4-iodobenzoic acids should be used as the starting substrates, because mixtures containing ...

Eco-friendly oxidative iodination of various arenes with sodium percarbonate as the oxidant.

Six easy laboratory procedures are presented for the oxidative iodination of various aromatics, mostly arenes, with either molecular iodine or potassium iodide (used as the sources of iodinating species, I+ or I3+), in the presence of sodium percarbonate(SPC), a stable, cheap, easy to handle, and eco-friendly commercial oxidant.

Hydrogen Peroxide, Peracetic Acid and Sodium Percarbonate

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
