Adducts of disilene (SiH/sub 2/=SiH/sub 2/) and silylsilylene (SiH/sub 3/SiH:) to butadiene have been found, in addition to the previously reported products from the reactions of recoiling silicon atoms in gaseous mixtures of phosphine (PH/sub 3/), butadiene (C-H/sub 2/=CH-CH=CH/sub 2/), and silane (SiH/sub 4/). The change in yields when neon moderator is present - the yield of the silylsilylene adduct increases while that of the disilene adduct decreases - is in accord with the formation of disilene via a silylsilylene intermediate. This is strong evidence for the rearrangement of silylsilylene to disilene: SiH/sub 3/SiH: ..-->.. SiH/sub 2/=SiH/sub 2/.
