α-Bromo propiophenone-d5 is a deuterated analog of α-bromo propiophenone, a chemical compound with the molecular formula C9D5BrO. It is a halogenated ketone, where the hydrogen atoms in the original compound are replaced with deuterium atoms, making it a useful compound for various applications in organic chemistry, particularly in the field of spectroscopy and isotope labeling. Deuterium labeling can enhance the sensitivity and resolution of spectroscopic techniques, such as NMR and IR spectroscopy, by providing distinct signals for the deuterated and non-deuterated species. α-BroMopropiophenone-d5 is often used in research to study reaction mechanisms, investigate the properties of molecules, and as a reference standard in analytical chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 87258-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,5 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87258-66:
(7*8)+(6*7)+(5*2)+(4*5)+(3*8)+(2*6)+(1*6)=170
170 % 10 = 0
So 87258-66-0 is a valid CAS Registry Number.

Base Catalysed Rearrangements involving Ylide Intermediates. Part 18. Competing , , and Rearrangements of Ammonium Ylides

Chantrapromma, Kan,Ollis, W. David,Sutherland, Ian O.

, p. 1049 - 1062 (2007/10/02)

The rearrangements of acyl stabilised ammonium ylides are, in several cases, accompanied by competing rearrangements and in one case by a rearrangement.For examples involving migrating benzyl or phenylethyl groups the mechanism of these rearrangements has been studied.Thus the competing , , and rearrangements of the ylide (12) are largely intramolecular, but the intermolecularity is as high as 28percent for the and rearrangements and 14percent for the rearrangement in methanol at 55 deg C.The competing and rearrangements of the optically active (29a) give products with predominant retention of the configuration of the migrating phenylethyl group, but the intramolecular stereoselectivity of the rearrangement is significantly greater than that of the rearrangement.These results are consistent with a radical pair pathway for all three modes of rearrangement.Suitably substituted acyl stabilised allylammonium ylides (55) rearrange by competing , and processes.
