A phenanthrene derivative is represented by a formula (1) below. In the formula (1), Ar
1
and Ar
2
each represent an aromatic hydrocarbon ring group having 6 to 18 carbon atoms for forming the ring. The aromatic hydrocarbon ring group contains none of anthracene skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton. R
1
represents a substituent, the number of which may be 0, 1 or more. R
1
may be bonded in any position of the phenanthrene skeleton. n and m each represent an integer of 1 to 3. k represents an integer of 0 to 8.

The one-step high-yield synthesis of 1,2-bis(trimethylsilyl)benzene from 1,2-dibromobenzene using tert-butyllithium and trimethylsilyltriflate is reported. A mechanistic investigation shows that 1,2-dilithiobenzene is not an intermediate in this reaction; the coexistence of trimethylsilyltriflate and tert-butyllithium at very low temperatures allows a sequence of bromine−lithium exchange and subsequent
Arynes were found to be inserted into a C(sp)–Br σ-bond of bromoalkynes in the presence of a copper catalyst, giving (alkynyl)bromoarenes in a straightforward manner.

A general method for the palladium-catalyzed formation of diaryl ethers is described. Electron-rich, bulky aryldialkylphosphine ligands, in which the two alkyl groups are either tert-butyl or 1-adamantyl, are the key to the success of the transformation. A wide range of electron-deficient, electronically neutral and electron-rich aryl bromides, chlorides, and triflates can be combined with a variety
描述了钯催化形成二芳基醚的一般方法。富含电子的、庞大的芳基二烷基膦配体,其中两个烷基是叔丁基或 1-金刚烷基,是转化成功的关键。使用氢化钠或磷酸钾作为碱,在 100 °C 的甲苯中,可以将各种缺电子、电子中性和富电子的芳基溴化物、氯化物和三氟甲磺酸酯与各种酚结合。膦配体庞大而碱性的性质被认为是提高二芳基醚从钯中还原消除的速率的原因。
