In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Direct Arylation as a Synthetic Tool for the Synthesis of Thiophene-Based Organic Electronic Materials, published in 2011-03-22, which mentions a compound: 58656-04-5, mainly applied to thiophene derivative aryl bromide palladium catalyst direct arylation; arylthiophene regioselective preparation organic electronic material formal synthesis, Safety of Tricyclohexylphosphonium tetrafluoroborate.
The efficient synthesis of thiophene based organic electronic materials can be carried out in high yields using simple starting materials by employing palladium-catalyzed direct arylation. The direct arylation method was applied to the (formal) synthesis of ten mols. that have exhibited promise for applications as optoelectronic materials. The syntheses feature the following advantages over traditional cross-coupling techniques: (1) higher yields, (2) fewer synthetic operations, (3) lower catalyst loadings, and (4) does not employ organometallic intermediates. The advantages of direct arylation make it an ideal strategy for the synthesis of thiophene containing organic electronic materials.
