Calculate Digit Verification of CAS Registry Number 133446-19:
(8*1)+(7*3)+(6*3)+(5*4)+(4*4)+(3*6)+(2*1)+(1*9)=112
112 % 10 = 2

Rhodium(II)-Catalyzed Cyclization Reactions of Alkynyl-Substituted α-Diazo Ketones

Padwa, Albert,Krumpe, Keith E.,Gareau, Yves,Chiacchio, Ugo

, p. 2523 - 2530 (2007/10/02)

Treatment of several o-alkynyl-substituted α-diazoacetophenone derivatives with rhodium(II) carboxylates results in the formation of substituted indenones.The simplest mechanism accounting for the results involves addition of a rhodium-stabilized carbenoi
