6209-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6209-75-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,0 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6209-75:
(6*6)+(5*2)+(4*0)+(3*9)+(2*7)+(1*5)=92
92 % 10 = 2
So 6209-75-2 is a valid CAS Registry Number.

Synthesis of functionalized polycyclic compounds: Rhodium(I)-catalyzed intramolecular cycloaddition of yne and ene vinylidenecyclopropanes

Lu, Bei-Li,Shi, Min

supporting information; experimental part, p. 12027 - 12031 (2012/02/03)

Three ring circus: The title reaction can efficiently provide functionalized polycyclic compounds containing cyclobutene (see scheme; PG=protecting group) or aza-cyclooctene moieties in a highly regio- and diastereoselective manner with moderate to good yields under mild reaction conditions. The scope and limitations are disclosed and plausible reaction mechanisms are discussed. Copyright

SYNTHESIS OF ISOCOUMARINS VIA THALLATION-OLEFINATION OF BENZOIC ACIDS

Larock, R. C.,Varaprath, S.,Lau, H. H.,Fellows, C. A.

, p. 5274 - 5284 (2007/10/02)

Benzoic acid and substituted benzoic acids are readily thallated by thallium(III) trifluoroacetate and subsequently reacted with palladium chloride and simple olefins, allylic halides, vinyl halides, or vinyl esters to give isocoumarins.The organic halide reactions are catalytic in palladium. 1,2- and 1,3-dienes also react catalytically to afford 4-alkylidene- and 3-vinyl-3,4-dihydroisocoumarins, respectively.Vinylcyclopropanes also afford 3-vinyl-3,4-dihydroisocoumarins.This highly convenient thallation-olefination approach appears quite general for the synthesis of isocoumarins.
