119405-88-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119405-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,0 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119405-88:
(8*1)+(7*1)+(6*9)+(5*4)+(4*0)+(3*5)+(2*8)+(1*8)=128
128 % 10 = 8
So 119405-88-8 is a valid CAS Registry Number.

Ru-catalyzed decarbonylative addition of aliphatic aldehydes to terminal alkynes

Guo, Xiangyu,Wang, Jun,Li, Chao-Jun

supporting information; scheme or table, p. 3176 - 3178 (2010/08/22)

(Figure Presented) A novel method for the formation of isolated C - C bonds was developed via a ruthenium-catalyzed decarbonylative addition of aliphatic aldehydes and alkynes. An unprecedented complete switch of chemoselectivity from aromatic aldehydes to aliphatic aldehydes was observed simpl y by using tri(2,4,6-trismethoxyphenyl)phosphine as ligand. A synthesis by this method of an insect sex pheromone was demonstrated.

DIRECT PREPARATION OF SUBSTITUTED OLEFINS FROM EPOXIDES UTILIZING LITHIUM TETRAALKYLCERATE

Ukaji, Yutaka,Fujisawa, Tamotsu

, p. 5165 - 5168 (2007/10/02)

Alkylated olefins were directly synthesized in good yields by the deoxygenation reaction of epoxides with concomitant introduction of the alkyl group using lithium tetraalkylcerate.Styreneoxide and (1-naphtyl)ethyleneoxide gave terminal olefins, while ethyleneoxide replaced by alphatic substituent, 1,2-epoxy-4-phenylbutane, afforded internal olefin.The utility of the present method was demonstrated in the one-step synthesis of a sesquiterpene, dehydro-α-curcumene.
