Coordination states of trihydrosilane ( E )‐ 1 , chlorodihydrosilane ( E )‐ 2 , and tetrahydrodisiloxane ( E , E )‐ 4 bearing 2‐(phenylazo)phenyl groups were revealed by X‐ray crystallographic analysis and NMR spectroscopy. Trihydrosilane ( E )‐ 1 with a tetracoordinate silicon showed higher reactivity with CuCl 2 than trihydrophenylsilane. Photoirradiation of ( E )‐ 2 and ( E , E )‐ 4 , which have pentacoordinate silicon atom(s), successfully gave the corresponding ( Z )‐isomers. Each reaction of trihydrosilane ( E )‐ 1 and tetrahydrodisiloxane ( E , E )‐ 4 with fluoride ion gave 1,2‐diphenylhydrazine through an intramolecular hydrosilylation.
