1-Phenyl-hepta-4,6-dien-1-in, also known as 1-phenyl-1,4-heptadiene, is an organic compound characterized by a seven-carbon chain with a phenyl group attached to the first carbon and a diene functional group (two conjugated double bonds) between the fourth and sixth carbons. This molecule is a conjugated diene, which means it has alternating single and double bonds, and it is part of the styrene family due to the presence of the phenyl ring. It is used in the synthesis of various chemicals and polymers, such as polystyrene and styrene-based copolymers, and is also found in some fragrances and flavorings. The compound is known for its reactivity, particularly in Diels-Alder reactions, where it can undergo cycloaddition with other dienes or dienophiles to form cyclic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 1012-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,1 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1012-11:
(6*1)+(5*0)+(4*1)+(3*2)+(2*1)+(1*1)=19
19 % 10 = 9
So 1012-11-9 is a valid CAS Registry Number.

Ruthenium-catalyzed transformation of 3-benzyl but-1-ynyl ethers into 1,3-dienes and benzaldehyde via transfer hydrogen

Yeh, Kuo-Liang,Liu, Bo,Lai, Yen-Ting,Li, Chia-Wen,Liu, Rai-Shung

, p. 4692 - 4694 (2007/10/03)

TpRuPPh3(CH3CN)2PF6 catalyzed the transformation of various 3-benzyl but-1-ynyl ethers into dienes and benzaldehyde at a catalyst loading of 5 mol %. This process represents an atypical pattern of transfer hydrogenation. This catalytic reaction can be applied to various derivatives of 2-ethynyl tetrahydrofurans and pyrans to cleave their ether rings and gives diene and tethered aldehyde functionalities, respectively.
