Abstract AR

حضرت سلسلة جديدة من مركبات التلوریوم العضوية المشتقة من 4, 4-- ثنائي هيدروکسي آزوبنزين و ذلك من مفاعله المركب (A) (3-HgC1-4-OH-C6H3N=NC6H4-OH) مع TeBr4 وP-CH3OC6H4TeBr3 معطياً المركبين(B̅) (3-(P-CH3OC6H4TeBr2)-4-OHC6H3-N=N-C6H4-OH) و(B) (3-TeBr3-4-OHC6H3N=NCH4-OH).

أدى اختزال المركب (B) بواسطة كبريتيد الصوديوم إلى تكوين المركب (C) (3-TeBr-4-OH-CH3N=N-C6H4-OH).

كما حضر المركب (D)(OH-C6H4-N=N-C6H3-4-OH-3Te)2 من اختزال المركب B أو C بواسطة الهيدرازين المائي.

إن اختزال المركب B̅ أدى إلى تكوين التلوريد (E) 3-(P-CH3OCH4Te)-4-OH-CH3N=N-C6H4-4-OH.

شخصت جميع المركبات المحضرة بواسطة أطياف الأشعة تحت الحمراء و أطياف الرنين النووي المغناطيسي للبروتون، و قياس درجة الانصهار (m.p.).

دلت الدراسة التوصيلية المولارية للمركبات الهالوجينية الجديدة (C, B̅, B) في مذيبي DMSO وDMF على أنها الكتروليتات ضعيفة في كلا المذيبين.

Abstract EN

A new series of organotellurium compounds derived from 4, -4-dihydroxy azobenzen have been prepared by the reaction of 3-HgC1-4-OH-C6H3N = NC6H4-OH (A) with TeBr4 and P-CH3OC6H4TeBr3 to give (3-(P-CH3OC6H4TeBr2)-4-OHC6H3-N = N-C6H4-OH) (B) and (3-TeBr3-4-OHC6H3N=NCH4-OH) (B) respectively, reduction of B by sodium sulphide gave the corresponding organotellurenyl compound (C), (3-TeBr-4-OH-CH3N=N-C6H4-OH).

Compound (D) (OH-C6H4-N=N-CH3-4-OH-3Te)2 has been prepared by reduction of compound B or C by hydrazine hydrate.

Reduction of B gave the corresponding telluride 3-(P-CH3OCH4Te)-4-OH-CH3N=N-C6H4-4-OH (E).

All compounds have been characterized, by IR and 1H NMR spectral data and meting point was determined.

The molar conductivities of the halogenated compounds (B, B ,C) in DMSO and DMF show some weak electrolytic behavior.
