In summary, a highly efficient ruthenium complex has
been developed for the undirected C2-selective silylation of
O- and S-heteroarenes with (TMSO)2MeSiH and Et3SiH.
High conversions and high TONs (∼2000) can be achieved
using low catalyst loadings. Moreover, a mild and practical
protocol has been described for the Hiyama−Denmark coupling
of heteroarylsilanes with aryl iodides.
