Usage

General Description

2-T-Butylthiophene is a type of organic compound that falls under the category of thiophenes. Thiophenes are sulfur analogues of the compound benzene, containing a five-membered aromatic ring with one sulfur atom. 2-T-Butylthiophene is a colorless liquid with a strong odor. As an organic compound, it consists of carbon, hydrogen, and sulfur atoms. Due to its aromatic nature, this chemical is often used in research and development settings, particularly in the synthesis of other complex compounds. Its exact properties such as toxicity, health effects, or environmental effects, however, may vary and are typically studied under controlled situations. The handling and use of 2-T-Butylthiophene should always be carried out with appropriate safety measures.

E-H (E = R3Si or H) bond activation by B(C6F 5)3 and heteroarenes; Competitive dehydrosilylation, hydrosilylation and hydrogenation

In the presence of B(C6F5)3 five-membered heteroarenes undergo dehydrosilylation and hydrosilylation with silanes. The former, favoured on addition of a weak base, produces H2 as a by-product making the process catalytic in B(C6F5) 3 but also enabling competitive heteroarene hydrogenation. the Partner Organisations 2014.

Catalytic transformations of alkylthiophenes

The transformations of alkylthiophenes in the presence of amorphous aluminosilicate and decationated zeolite HNaY were studied. Substituted thiophenes with R = 2- and 3-Me, 2-Et, and 2-iso-Pr undergo dealkylation to thiophene with close rates, migration of the alkyl group from the 9α- to the β-position of the thiophene ring (or in the opposite direction with an elevated rate), and decomposition with H2S elimination. The dealkylation rate of 2-substituted thiophenes with a branched-chain radical (R = iso-Pr, terf-Bu) is much higher and the elimination rate with this radical is lower than those for normal-chain radicals; the isomerization step is virtually absent. Di-, tri-, and tetrasubstituted thiophenes with R = Et and iso-Pr undergo stepwise dealkylation, which is facilitated by an increase in the degree of substitution on the thiophene ring. Thiophene and its lower homologues can be obtained by the transformation of a mixture of high-molecular thiophenes. Copyright
