The acylation reaction of BN-arenes has been studied using BN-arene and acyl chloride in good to excellent yields, which led to the first synthesis of indanone BN-analogue. The BN-aromatic ketone products have been characterized by ¹H NMR spectroscopy with their molecular structures unambiguously confirmed by X-ray crystallography. The annulation reaction of BN-arenes promoted by AgBF₄ occurs in a completely regioselective manner and a mechanism for this transformation is proposed.

BN取代的芳烃的Friedel-Crafts酰化反应

已经使用BN-芳烃和酰氯以良好至优异的产率研究了BN-芳烃的酰化反应，这导致了茚满酮BN-类似物的首次合成。BN-芳族酮产物已通过¹ H NMR光谱进行了表征，其分子结构已通过X射线晶体学明确证实。AgBF ₄促进的BN芳烃的环化反应以完全区域选择性的方式发生，并提出了这种转变的机理。
