Bis-(trimethylsilyl)-monochlor-diphenylsilyl-amin, also known as (ClSiPh2)N(SiMe3)2, is a complex organosilicon compound characterized by its unique structure. It features a central silicon atom bonded to two trimethylsilyl groups (SiMe3) and a diphenylsilyl group (SiPh2), with an additional chlorine atom attached to the diphenylsilyl moiety. The molecule also contains an amino group (NH2) bonded to the central silicon atom, which can participate in various chemical reactions. Bis-(trimethylsilyl)-monochlor-diphenylsilyl-amin is of interest in the field of organosilicon chemistry due to its potential applications in the synthesis of silylating agents, ligands for transition metal complexes, and as intermediates in the preparation of more complex organosilicon compounds. Its stability, reactivity, and the ability to form various derivatives make it a valuable component in the development of new materials and chemical processes.

Check Digit Verification of cas no

The CAS Registry Mumber 1586-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,8 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1586-70:
(6*1)+(5*5)+(4*8)+(3*6)+(2*7)+(1*0)=95
95 % 10 = 5
So 1586-70-5 is a valid CAS Registry Number.

Reaktionen von Bis(trimethylsilyl)amino-substituierten Chlorsilanen [(Me3Si)2N]Me2-nPhnSiCl (n=0, 1, 2) mit Lithium - Darstellung von Bis(trimethylsilyl)amino-substituierten Silyllithiumverbindungen und Disilanen

The bis(trimethylsilyl)amino-substituted chlorosilanes [(Me3Si)2N]Me2-nPhnSiCl (1: n=0, 2: n=1, 3: n=2) were allowed to react with lithium metal in tetrahydrofuran. 1 slowly reacts at room temperature to the homocoupling product {[(Me3Si)2N]Me2Si}2 (4). An equimolar mixture of 1 and Me3SiCl gives 4 and the cross-coupling product [(Me3Si)2N]Me2Si-SiMe3 (5). The reaction of 2 at -78°C leads to formation of bis(trimethylsilyl)aminosilyllithium [(Me3Si)2N]MePhSiLi (6), which reacts with Me3SiCl and 2 resp. to the corresponding disilanes [(Me3Si)2N]MePhSi-SiMe3 (7) and {[(Me3Si)2N]MePhSi}2 (8). 6 undergoes partially self-condensation at -40 and 0°C and the disilanyllithium [(Me3Si)2N]MePhSi-SiMePhLi (9) is formed. 3 reacts rapidly at 0 and -20°C to give the silyllithium [(Me3Si)2N]Ph2SiLi (12). Treatment of 12 with Me3SiCl and 3 resp. affords the disilanes [(Me3Si)2N]Ph2Si-SiMe3 (13) and {[(Me3Si)2N]Ph2Si}2 (14). The disilane R[(Me3Si)2NMeSi-SiMe3 (11) (R=3,4,5,6-tetrakis(trimethylsilyl)cyclohex-1-enyl) is obtained by reaction of a mixture of 2 and Me3SiCl in molar ratio 1:5 with 6 equivalents of lithium in THF. The crystal structure of 11 is reported. Zusammenfassung Die bis(trimethylsilyl)amino-substituierten Chlorsilane [(Me3Si)2N]Me2-nPhnSiCl (1: n=0, 2: n=1, 3: n=2) wurden mit Lithium in Tetrahydrofuran umgesetzt. 1 reagiert langsam bei Raumtemperatur zum Homokupplungsprodukt {[(Me3Si)2N]Me2Si}2 (4). Ein aequimolares Gemisch von 1 und Me3SiCl ergibt neben 4 auch das Kreuzkupplungs-produkt [(Me3Si)2N]Me2Si-SiMe3 (5). Die Reaktion von 2 bei -78°C fuehrt zum Bis(trimethylsilyl)aminosilyllithium [(Me3Si)2N]MePhSiLi (6), bei dessen Umsetzung mit Me3SiCl bzw. 2 die entsprechenden Disilane [(Me3Si)2N]MePhSi-SiMe3 (7) und {[(Me3Si)2N]MePhSi}2 (8) entstehen. Bei -40 und 0°C unterliegt 6 partiell einer Eigenkondensation, und das Disilanyllithium [(Me3Si)2N]MePhSi-SiMePhLi (9) wird gebildet. 3 reagiert bei 0 und -20°C schnell zum Silyllithium [(Me3Si)2N]Ph2SiLi (12). Die Reaktion von 12 mit Me3SiCl bzw. 3 ergibt die entsprechenden Disilane [(Me3Si)2N]Ph2Si-SiMe3 (13) und {[(Me3Si)2N]Ph2Si}2 (14). Bei der Reaktion eines Gemisches von 2 und Me3SiCl im Molverhaeltnis 1:5 mit 6 Aequivalen-ten Lithium in THF entsteht das Disilan-R[(Me3Si)2NMeSi-SiMe3 (11) (R=3,4,5,6-Tetrakis(trimethylsilyl)cyclohex-1-enyl). Die Kristallstruktur von 11 ist beschrieben.
