689-67-8 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 689-67-8 differently. You can refer to the following data:
1. Geranylacetone occurs in (5Z)-trans
as well as in (5E)-trans form and has been identified in fruits and in essential oils.
It is a colorless liquid with a fresh, green, slightly penetrating, rose-like odor.
Geranylacetone is an intermediate in the synthesis of other fragrance substances.
It is mainly produced from linalool. Another route starts from myrcene,
to which methyl acetoacetate is added under rhodium catalysis; geranylacetone is
subsequently obtained after saponification and decarboxylation. It is used
in perfumery in rose compositions, for example, in soap perfumes.
2. 6,10-Dimethyl-5,9-undecadien-2-one has a green and rosy floral odor and fresh-floral, light, but rather penetrating
sweet-rosy, slightly green, magnolia-like odor. It blends well in lavender and fruity notes, where it imparts a clean and natural character. It helps to round out floral bouquets
Uses
It is used as a flavoring agent and adjuvant. It is also employed as a substance, extract, or preparation for diffusing or imparting an agreeable or attractive smell.
Application
Geranylacetone is an intermediate in nerolidol synthesis. It is used in perfumery in rose compositions, for example, in soap perfumes.
General Description
6,10-Dimethyl-5,9-undecadien-2-one is one of the key volatile flavor compounds of tomato and certain species of mushroom.
Safety Profile
A skin irritant. When
heated to decomposition it emits acrid
smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 689-67-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 689-67:
(5*6)+(4*8)+(3*9)+(2*6)+(1*7)=108
108 % 10 = 8
So 689-67-8 is a valid CAS Registry Number.

Capturing the Monomeric (L)CuH in NHC-Capped Cyclodextrin: Cavity-Controlled Chemoselective Hydrosilylation of α,β-Unsaturated Ketones

The encapsulation of copper inside a cyclodextrin capped with an N-heterocyclic carbene (ICyD) allowed both to catch the elusive monomeric (L)CuH and a cavity-controlled chemoselective copper-catalyzed hydrosilylation of α,β-unsaturated ketones. Remarkably, (α-ICyD)CuCl promoted the 1,2-addition exclusively, while (β-ICyD)CuCl produced the fully reduced product. The chemoselectivity is controlled by the size of the cavity and weak interactions between the substrate and internal C?H bonds of the cyclodextrin.
A ruthenium complex compound for the selective hydrogenation of the dienone method
-
Paragraph 0050-0052, (2019/07/04)
The invention provides a selective hydrogenation of ruthenium complex α, γ - unsaturated dienone method, and in particular relates to a method for using the hydrogen in the catalyst under the action of the α, γ - unsaturated dienone is reduced to the corresponding γ - unsaturated ketone of the method, the catalyst employed for ruthenium complex, a ruthenium precursor and the ligand in-situ prepared. Major advantage of this invention is characterized in that the catalyst is composed of metal precursor and the ligand in-situ prepared, simple operation, high catalyst activity; pyridine, quinoline nitrogen-containing aromatic heterocycle such as the adding of the poisoned medicinal preparation, effectively restraining the product γ - unsaturated ketone transition hydrogenation reaction, an excellent selectivity, the cost is low.
