817-88-9 Usage
Chemical Properties
(E) and (Z)-4,8-Dimethyl-3,7-nonadien-2-one has a floral-fruity odor. In a U.S. patent, the olfactory properties of this
compound have been described as fruity, fresh, acetate, rose oxide, aqueous grapefruit, melon, fresh, bergamot and rosemary
Synthesis
Prepared by the reaction of 8-dimethyl-3,7-nonadien-2-ol in the presence of a catalyst and hydrogen acceptor (alphaamylcinnamaldehyde and aluminum isopropoxide). 8-Dimethyl-3,7-nonadien-2-ol may be synthesized by a Grignard reaction from citral and methylmagnesium chloride.
Check Digit Verification of cas no
The CAS Registry Mumber 817-88-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 817-88:
(5*8)+(4*1)+(3*7)+(2*8)+(1*8)=89
89 % 10 = 9
So 817-88-9 is a valid CAS Registry Number.

Pd(II)-hydrotalcite-catalyzed oxidation of alcohols to aldehydes and ketones using atmospheric pressure of air
Kakiuchi,Maeda,Nishimura,Uemura
, p. 6620 - 6625 (2007/10/03)
A heterogenized Pd catalyst, Pd(II)-hydrotalcite (palladium(II) acetate-pyridine supported by hydrotalcite) catalyzes the aerobic oxidation in toluene of a variety of primary and secondary alcohols into the corresponding aldehydes and ketones in high yields using atmospheric pressure of air as a sole oxidant under mild conditions. This catalyst is also effective for the oxidation of allylic alcohols, especially such as geraniol and nerol, without any isomerization of an alkenic part. The catalyst can be easily prepared from all commercially available reagents and reused several times.
