General Description
(E)-pent-2-en-1-yl acetate is a chemical compound with the molecular formula C7H12O2. It is an ester, specifically an acetate, that is commonly used in the production of perfumes and flavorings due to its pleasant, fruity odor. (E)-pent-2-en-1-yl acetate can be found naturally in a variety of fruits, including apples, bananas, and melons, and is also produced synthetically for use in the food and fragrance industries. (E)-pent-2-en-1-yl acetate is known for its sweet, fruity aroma and is often used to add a natural and fresh scent to consumer products. However, it should be handled with care as it is flammable and can cause irritation if it comes into contact with the skin or eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 42125-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,2 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42125-28:
(7*4)+(6*2)+(5*1)+(4*2)+(3*5)+(2*2)+(1*8)=80
80 % 10 = 0
So 42125-28-0 is a valid CAS Registry Number.

Achieving control over the branched/linear selectivity in palladium-catalyzed allylic amination
Dubovyk, Igor,Watson, Iain D. G.,Yudin, Andrei K.

Palladium-catalyzed reaction of unsymmetrical allylic electrophiles with amines gives rise to regioisomeric allylic amines. We have found that linear products result from the thermodynamically controlled isomerization of the initially formed branched products. The isomerization is promoted by protic acid and active palladium catalyst. The use of base shuts down the isomerization pathway and allows for the preparation and isolation of branched allylic amines. Solvent plays a key role in achieving high kinetic regioselectivity and in controlling the rate of isomerization. The isomerization can be combined with ring-closing metathesis to afford the synthesis of exocyclic allylic amines from their endocyclic precursors.
