3944-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3944-16-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3944-16:
(6*3)+(5*9)+(4*4)+(3*4)+(2*1)+(1*6)=99
99 % 10 = 9
So 3944-16-9 is a valid CAS Registry Number.

?-Silicon-effect-promoted intermolecular site-selective C(sp3)-H amination with dirhodium nitrenes

Ninomiya, Ryo,Arai, Kenta,Chen, Gong,Morisaki, Kazuhiro,Kawabata, Takeo,Ueda, Yoshihiro

supporting information, p. 5759 - 5762 (2020/06/03)

A dirhodium-catalyzed, ?-selective C-H amination of organosilicon compounds has been developed. Primary C(sp3)-H bonds of silylethyl groups and secondary C(sp3)-H bonds of silacycloalkanes can be selectively converted to C-N bonds at the ?-position of the silicon atoms. The experimental data and theoretical calculations indicate that the strong s-donor ability of the carbon-silicon bonds is responsible for the ?-selectivity. Kinetic isotope effects clearly demonstrate that the C-H bond cleavage step is not turnover-limiting, but selectivity-determining.

UEBER DIE AUSTAUSCHBARKEIT VON METHYL- UND PHENYLGRUPPEN AM SILICIUM VON SILACYCLOPENTAN BEI DER EINWIRKUNG VON ALKYL- UND ARYLLITHIUMVERBINDUNGEN IN DIETHYLETHER ODER TETRAHYDROFURAN

Maercker, Adalbert,Stoetzel, Reinhard

, p. C57 - C63 (2007/10/02)

A degenerate ligand exchange, presumably via an ate-complex intermediate, takes place upon treatment of 1,1-dimethyl- (3) and 1,1-diphenyl-silacyclopentane (17) in THF-d8 with perdeuteriomethyllithium (4-d3) or perdeuteriophenyllithium (15-d5), respective
