Hiyama Cross-Coupling of Chloro-, Fluoro-, and MethoxypyridyltrimethylsiRoom-Temperature Novel Access to Functional Bi(het)aryl. — The intro28- 151 lanes:
duction of electron-withdrawing substituents on the pyridine ring of 2-trimethylsilylpyridines makes them useful reactive partners in the Hiyama cross-coupling. It is performed cleanly at room temperature giving a novel access to functional bi(het)aryls.
The α-position of the trimethylsilyl group to the pyridine nitrogen is crucial. In all other
cases desilylated products are formed. — (PIERRAT, P.; GROS*, P.; FORT, Y.; Org.
