1184-77-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1184-77-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1184-77:
(6*1)+(5*1)+(4*8)+(3*4)+(2*7)+(1*7)=76
76 % 10 = 6
So 1184-77-6 is a valid CAS Registry Number.

Chemistry of heavy carbene analogues R2M (M = Si, Ge, Sn). 12. Concerted and nonconcerted insertion reactions of the germylene Me2Ge into the carbon-halogen bond

K?cher, Jürgen,Lehnig, Manfred,Neumann, Wilhelm P.

, p. 1201 - 1207 (2008/10/08)

During the reaction of Me2Ge with CCl3X (X = Cl, Br), PhCH2X (X = Br, I), and Ph2CHCl, 1H CIDNP is observed in the products of net insertion of Me2Ge into the carbon-halogen bond and in Me2GeX2 (X = Cl, Br). It is concluded that a two-step radical reaction takes place by an abstraction-recombination mechanism. No reaction takes place with alkyl halides that have a C-X bond dissociation energy of more than about 70 kcal/mol. Me2Ge is generated thermally at 70-95°C or photochemically from the 7-germabenzonorbornadiene 1 and reacts in both cases in the singlet state. The activation energy for forming Me2Ge from 1 is 19 kcal/mol for the reaction with CCl4. Insertion products are also formed with the alkenyl halides CH2=CHCH2X, PhCH=CHX (X = Cl, Br), and 2-bromobut-2-ene, but without showing CIDNP effects. Since Me2GeX2 was not found either, Me2Ge reacts in these cases in a nonradical manner. It does not react with 1-chlorocyclohexene, but it does react with Me2GeX2 under formation of digermanes and/or oligogermanes without CIDNP.

The Reaction of Germanium Atoms with Organic Halides

Mochida, Kunio,Tashiro, Kumiko

, p. 1105 - 1108 (2007/10/02)

Co-condensation of thermally evaporated germanium vapor with organic halides yields a mixture of trihalogermyl derivatives and tetrahalogermanes as major products.The nature of these reactions is discussed.
