Summary

Under matrix conditions (Ar, 10 K) silicon atoms do not react spontaneously with methane. An additional activation by irradiation is necessary to produce silene and methylsilylene. In contrast to the behavior of methane, silane is attacked by Si atoms with formation of disilene and silylsilylene (7-S), even at 10 K. Both compounds have been detected for the first time and can be interconverted photochemically. Photoexcitation of disilene also leads to elimination of H2 yielding disilyne and formation to small quantities of a new isomer, which is tentatively assigned to a doubly bridged structure.
