资源简介：
A small
series of S- and N-heterocyclic 1,2-bis(trimethylsilylethynyl)arenes
(2, 9, and 12) react with the
strongly electrophilic borane B(C6F5)3 in consecutive 1,1-carboboration sequences to benzannulated heterocyclic
systems. With this approach, highly substituted carbazole (6), benzothiophene (10), and quinoline (14) derivatives can be synthesized. While benzannulation occurs in
all three cases, the reactions are quite different in detail. Finally,
one-pot deborylation reactions lead to hydroxy-hetarenes, as demonstrated
for the hydroxy-carbazole 7 and the hydroxy-benzothiophene 11.
