155570-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 155570-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,7 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155570-15:
(8*1)+(7*5)+(6*5)+(5*5)+(4*7)+(3*0)+(2*1)+(1*5)=133
133 % 10 = 3
So 155570-15-3 is a valid CAS Registry Number.

Chemical and photochemical approaches to amino(aryl) silylenes

Corriu, Robert,Lanneau, Gerard,Priou, Christian,Soulairol, Florence,Auner, Norbert,et al.

, p. 55 - 68 (2007/10/02)

Generation by two different methods of silylenes stabilized by o-amino(aryl) groups is reported.The halodemetallation of difluoro- or dichloro-silanes with Li metal or lithium-naphthalene gave the same product, a stabilized sila-ylide (hypercoordinated silylene).Intramolecular Lewis base stabilization is not sufficient to isolate a monomeric species.The silylenes, however, have been trapped with 2,3-dimethylbutadiene.An unexpected intramolecular rearrangement to silaacenaphthene has been observed in the case of a six-membered ring amino(aryl) coordinated silylene.Photolysis of o-1--2-benzene produced, among other products, Me3SiSiMe3 and the sila-ylide, which has been trapped with Et3SiH and dimethylbutadiene.Our mechanistic interpretation is supported by spectral observation of the photochemically generated reaction intermediates in a 3-methylpentane glass at low temperature. Key words: Silylene; Sila-ylide; Amino-aryl; Alkali metals; Stabilization; Photochemistry
