3196-56-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3196-56-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3196-56:
(6*3)+(5*1)+(4*9)+(3*6)+(2*5)+(1*6)=93
93 % 10 = 3
So 3196-56-3 is a valid CAS Registry Number.

Methanolysis of 4-Methyl-2,6,7-trioxa-1-phosphabicyclooctane 1-Oxide and 1-Sulfide: Mechanistic and Stereochemical Considerations

Kim, Jeong Han,Gallagher, Michael J.,Toia, Robert F.

, p. 715 - 722 (2007/10/02)

Methanolysis of 4-methyl-2,6,7-trioxa-1-phosphabicyclooctane 1-oxide and 4-methyl-2,6,7-trioxa-1-phosphabicyclooctane 1-sulfide have been studied by 31P n.m.r. spectroscopy.The trans-2-methoxy-5-methyl-1,3,2-dioxaphosphorinane-r-5-methanol 2-oxide and trans-2-methoxy-5-methyl-1,3,2-dioxaphosphorinane-r-5-methanol 2-sulfide are the initially formed products, respectively, but with time a product mixture comprising the trans- and cis-isomers and the acyclic dimethyl phosphate is formed.Methanolysis of the isolated trans-isomer, and of the isolated acyclic dimethyl phosphate under the same reaction conditions, suggests that the cis-isomer results from a recyclization reaction, rather than from the alternative ring opening of the bicyclic compound.

STEREOELECTRONIC EFFECTS IN THE HYDROLYSIS OF PHOSPHONIUM IONS FROM ACYCLIC AND BICYCLIC PHOSPHOROTHIONATES

Farschtschi, Nasser,Gorenstein, David G.,Fanni, Tahsin,Taira, Kazunari

, p. 93 - 104 (2007/10/02)

The alkaline hydrolysis of the bicyclic phosphonium ion 1-methyl-3,5,8-trioxabicyclo-octane-4-methylthiophosphonium ion 1 proceeds mainly with P-O bond cleavage as shown by hydrolysis in 18O labeled water to form the cyclic epimers cis- and trans-2-methylmercapto-2-oxo-5-hydroxymethyl-1,3,2-dioxaphosphorinane (2/3) in addition to the bicyclic phosphate, 1-methyl-4-phospha-3,5,8-trioxabicyclooctane-4-oxide, 4.The trans epimer 3 is formed after pseudorotation of the triagonal bipyramid (tbp) intermediate and is the predominant initial product.This could be explained by deprotonation of the initial neutral tbp intermediate 5 followed by fast pseudorotation to give the more stable anionic tbp 5'in which the negatively charged oxygen is placed in the equatorial position of the intermediate.In contrast, the acyclic analogue triethoxy(methylthio)phosphonium ion undergoes alkaline hydrolysis with 100percent P-S bond cleavage.It is very unusual to observe P-O bond cleavage competitive with P-S bond cleavage as we have demonstrated for the hydrolysis of the bicyclic thiophosphonium ion, 1.These results are supportive of the stereoelectronic effect hypothesis.
