A bithiophene?alkyne-based compound was synthesized and first utilized as a ligand for the selective hydrosilylation of allenes with primary and secondary phenylsilanes. It shows high selectivity towards the production of branched allylsilanes with a wide range of allenes. It is worth mentioning that the catalytic loading of the palladium can be reduced to 500 ppm. This work opens a new front of using bidentate thiophene ligand as a reaction promoter in transition-metal-catalyzed organic reaction. (Figure presented.).

The transition-metal-catalyzed oxidative cross-coupling between two coupling partners with similar structure and electronic characteristics remains a challenge owing to difficulty in suppressing undesired homo-couplings. We herein report a Pd-catalyzed oxidative cross-coupling between two thiophenes under mild reaction conditions. This approach can also be extended to furans. Some notable advantages of this reaction lie in its synthetic simplicity with the omission of the toxic stannanes coupling partner and excellent functional-group compatibility. The features of this protocol make it an ideal strategy for the construction of a 2,2′-thiophene-thiophene linkage of interest in electronic and optoelectronic materials.

α,ω-Bis[Co2(CO)6{μ-η 2:η2-C(R)≡C}]oligothiophene derivatives (6-10), in which two dicobalt hexacarbonyl acetylides are π-conjugated onto both terminals of the oligothiophene, were prepared by the reaction of the
