Diethyl(diphenyl)germane, also known as bis(diphenyl)diethylgermane, is an organogermanium compound with the chemical formula C16H18Ge. It is a colorless, crystalline solid that is soluble in organic solvents. diethyl(diphenyl)germane is characterized by its two diphenyl groups (Ph2) and two diethyl groups (Et2) attached to a central germanium atom, forming a tetrahedral geometry around the germanium. Diethyl(diphenyl)germane is primarily used as a precursor in the synthesis of various organogermanium compounds and as a ligand in organometallic chemistry. It is also of interest in materials science for its potential applications in electronic devices and as a component in polymers. The compound is typically synthesized through the reaction of diphenylgermane with ethylmagnesium bromide, followed by hydrolysis. Due to its reactivity and potential health and environmental risks, it is important to handle diethyl(diphenyl)germane with care, using appropriate safety measures.

Check Digit Verification of cas no

The CAS Registry Mumber 2945-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2945-43:
(6*2)+(5*9)+(4*4)+(3*5)+(2*4)+(1*3)=99
99 % 10 = 9
So 2945-43-9 is a valid CAS Registry Number.

Preparation and Some Reactions of Diarylgermylenedialkali Metals

Mochida, Kunio,Matsushige, Naoki,Hamashima, Mari

, p. 1443 - 1447 (2007/10/02)

The reactions of diarylgermanes with alkali metals in HMPA/THF or THF were found to give the corresponding diarylgermylenedialkali metals in high yields.Diphenylgermylenedipotassium reacted with aryl halides or carbonyl compounds to give reduction products predominantly.With alkyl halides, diphenylgermylenedipotassium gave mainly substitution products.
