2-phenyl-5-(prop-1-yn-1-yl)thiophene is an organic compound characterized by a thiophene ring, which is a five-membered aromatic ring containing one sulfur atom. In this specific compound, the thiophene ring is substituted with a phenyl group at the 2nd position and a prop-1-yn-1-yl group at the 5th position. The phenyl group is a benzene ring, and the prop-1-yn-1-yl group is a propargyl group, which consists of a three-carbon chain with a triple bond at one end. 2-phenyl-5-(prop-1-yn-1-yl)thiophene is known for its potential applications in the synthesis of various organic compounds and materials, such as pharmaceuticals and polymers, due to its unique structure and reactivity.

1204-82-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1204-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1204-82:
(6*1)+(5*2)+(4*0)+(3*4)+(2*8)+(1*2)=46
46 % 10 = 6
So 1204-82-6 is a valid CAS Registry Number.

Palladium-catalyzed direct alkynylation of thiophenes with halosilylacetylenes

Kato, Hayate,Tsukada, Naofumi

supporting information, (2021/02/20)

Silylethynylthiophenes were obtained from palladium-catalyzed alkynylation of various thiophenes with 1-halo-2-silylacetylenes. The α-position of thiophenes was alkynylated with high regioselectivity. The terminal silyl groups of products could be replaced by several functional groups.

Regiospecific palladium-catalyzed cross-coupling reactions using the operational equivalent of 1,3-dilithiopropyne

A regiospecific palladium-catalyzed cross-coupling reaction using the operational equivalent of the dianion 1,3-dilithiopropyne, with aromatic iodides is reported. This reaction gives high yields of 1-propyn-1-yl-benzenes and 2-(propyn-1-yl)thiophenes in

Photochemical Synthesis of Bithienyl Derivatives

, p. 1777 - 1780 (2007/10/02)

The application of a photochemical arylation of thienyl derivatives to the synthesis of bithienyl compounds is reported.The syntheses of 5-phenyl-2-propynylthiophene and 5-but-3-en-1-ynyl-2,2'-bithienyl are described using as starting materials a phenylthienyl and a bithienyl derivative obtained by this method.Furhtermore, the photochemical synthesis of halogenobithienyl ketones via the photochemical coupling of a halogenothiophene and 2-acetyl-5-iodothiophene is describred.This methodology furnishes a new approach to the synthesis of natural bithienyls.All the synthesized compounds are singlet oxygen photosensitizers, and are, therefore, potentially bioactive compounds.
