The first synthesis and crystalstructures of five-membered ring aryne complexes, Ni(dcpe)(η2-thiophyne) and Ni(dcpe)(η2-benzo[b]thiophyne), are described. The aryne fragments retain considerable aromatic character and the two coordinated carbon atoms exhibit distinct reactivity due to their asymmetric nature.
的五元环芳炔络合物第一合成和晶体结构,镍(η(DCPE)2 -thiophyne)和Ni(DCPE)(η 2 -苯并[ b ] thiophyne),中描述。亚芳基片段保留了相当大的芳族特征,并且两个配位的碳原子由于它们的不对称性质而显示出不同的反应性。

Selective Metallation of 3-Halothiophenes: Practical Methods for the Synthesis of 2-Bromo-3-formylthiophene
Selective lithiation of 3-bromothiophene was accomplished under controlled conditions without formation of undesired thienyllithium compounds. A thienyl Grignard reagent derived from 2-bromo-3-iodothiophene was transformed into 2-bromo-3-formylthiophene in high selectivity by formylation with dimethylformamide (DMF) at optimal reaction temperature.
