58243-50-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58243-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,2,4 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58243-50:
(7*5)+(6*8)+(5*2)+(4*4)+(3*3)+(2*5)+(1*0)=128
128 % 10 = 8
So 58243-50-8 is a valid CAS Registry Number.

Synthesis of 9-alkylidene-9H-fluorenes by a novel, palladium-catalyzed cascade reaction of aryl halides and 1-aryl-1-alkynes

Larock,Tian

, p. 7372 - 7379 (2007/10/03)

In the presence of a palladium catalyst and NaOAc, aryl iodides react with 1-aryl-1-alkynes to afford 9-alkylidene-9H-fluorenes in good yields. The products from this reaction are highly dependent on the base employed. This process appears to involve (1)

Synthesis of 9-alkylidene-9H-fluorenes by a novel palladium-catalyzed rearrangement

Tian, Qingping,Larock, Richard C.

, p. 3329 - 3332 (2007/10/03)

(matrix presented) In the presence of a palladium catalyst and NaOAc, aryl iodides react with 1-aryl-1-alkynes to afford 9-alkylidene-9H-fluorenes in good yields. This process appears to involve (1) oxidative addition of the aryl iodide to Pd(0), (2) alkyne insertion, (3) rearrangement of the resulting vinylic palladium intermediate to an arylpalladium species, and (4) aryl-aryl coupling with simultaneous regeneration of the Pd(0) catalyst.
