Purification Methods
Commercial material can contain up to 2% of poly-1-vinylnaphthalene. Fractionally distil it under reduced pressure using a spinning-band column, dry it with CaH2 and again distil it under vacuum. Store it in sealed ampoules in a freezer. It has max (cyclohexane) at 210 and 320nm. The picrate has m 105-106o. [Beilstein 5 H 585, 5 III 1773, 5 IV 1833.] It is an irritant.
Check Digit Verification of cas no
The CAS Registry Mumber 826-74-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 826-74:
(5*8)+(4*2)+(3*6)+(2*7)+(1*4)=84
84 % 10 = 4
So 826-74-4 is a valid CAS Registry Number.

Indene formation upon borane-induced cyclization of arylallenes, 1,1-carboboration, and retro-hydroboration

We herein report the reaction of arylallenes with tris(pentafluorophenyl)borane that yields pentafluorophenyl substituted indenes. The tris(pentafluorophenyl)borane induces the cyclization of the allene and transfers a pentafluorophenyl ring in the course of this reaction. A Hammett plot analysis and DFT computations indicate a 1,1-carboboration to be the C-C bond-forming step.
