Calculate Digit Verification of CAS Registry Number 1574520-89:
(9*1)+(8*5)+(7*7)+(6*4)+(5*5)+(4*2)+(3*0)+(2*8)+(1*9)=180
180 % 10 = 0
So 1574520-89-0 is a valid CAS Registry Number.

Synthesis of 2,5-Diaryl-1,5-dienes from Allylic Bromides Using Visible-Light Photoredox Catalysis

Pratsch, Gerald,Overman, Larry E.

, p. 11388 - 11397 (2015)

Visible-light photoreductive coupling of 2-arylallyl bromides in the presence of the photocatalyst Ru(bpy)3(PF6)2, a Hantzsch ester, and i-Pr2NEt gives 2,5-diaryl-1,5-dienes in high yield. This method avoids the use of stoichiometric metal reductants and is compatible with the presence of halogen, alkyl, electron-donating, and electron-withdrawing substituents on the aromatic ring.
