81194-40-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81194-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,9 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81194-40:
(7*8)+(6*1)+(5*1)+(4*9)+(3*4)+(2*4)+(1*0)=123
123 % 10 = 3
So 81194-40-3 is a valid CAS Registry Number.

Synthesis of Allylsilanes via Nickel-Catalyzed Cross-Coupling of Silicon Nucleophiles with Allyl Alcohols

Yang, Bo,Wang, Zhong-Xia

, p. 7965 - 7969 (2019/10/19)

NiCl2(PMe3)2-catalyzed reaction of allyl alcohols with silylzinc reagents, including PhMe2SiZnCl, Ph2MeSiZnCl, and Ph3SiZnCl, was performed, achieving allylsilanes in high yields. Aryl- and heteroaryl-substituted allyl alcohols, (E)-3-arylprop-2-en-1-ols, 1-aryl-prop-2-en-1-ols, and (E)-1-phenylpent-1-en-3-ol can be employed in the transformation. A range of functional groups as well as heteroaryl groups were tolerated. Reaction exhibited high regioselectivity and E/Z-selectivity when 1- or 3-aryl-substituted allyl alcohols were used as the substrates. Reaction of chiral allyl alcohol, (S,E)-1-phenylpent-1-en-3-ol, yielded a configuration-inversion product (R,E)-dimethyl(phenyl)(1-phenylpent-1-en-3-yl)silane.

Catalytic coupling of N-benzylic sulfonamides with silylated nucleophiles at room temperature

Yang, Bai-Ling,Tian, Shi-Kai

supporting information; experimental part, p. 6180 - 6182 (2010/10/20)

In the presence of 2-10 mol% of Tf2NH, a range of N-benzylic sulfonamides smoothly react with allylic, propargylic, benzylic, or hydrido silanes at room temperature via sp3 carbon-nitrogen bond cleavage to afford structurally diverse products in moderate to excellent yields and with high chemo- and regioselectivity.

Direct substitution of the hydroxy group in alcohols with silyl nucleophiles catalyzed by indium trichloride

Yasuda, Makoto,Saito, Takahiro,Ueba, Masako,Baba, Akio

, p. 1414 - 1416 (2007/10/03)

Straightforward substitution: An excellent combination of a silyl nucleophile and indium catalyst was used to accomplish the dehydroxylation/ alkylation of alcohols under nearly neutral conditions (see scheme, Si = silyl group) even though this type of reaction usually requires at least an equimolar amount of acid.
