A direct metal-free transformation from arylamines to aryl naphthalene-1,8-diamino boronamides, a type of masked boronic acid, has been developed based on Sandmeyer-type reactions. A nonsymmetrical diboron reagent, B(pin)-B(dan), was utilized as the borylating reagent, and the B(dan) moiety was transferred to the aim products selectively. This conversion tolerated a series of functional groups, including
已经基于 Sandmeyer 型反应开发了从芳胺到芳基萘-1,8-二氨基硼酰胺(一种掩蔽硼酸)的直接无金属转化。非对称二硼试剂 B(pin)-B(dan) 用作硼酸化试剂,B(dan) 部分选择性地转移到目标产品。这种转化耐受一系列官能团,包括氯、溴、氟、酯、羟基、氰基和酰胺。
