A silicon-silicon triple bond surrounded by bulky terphenyl groups
In search of a stable disilyne, effects of bulky 2,6-bis(2,4,6-triisopropylphenyl)phenyl (Ar*) groups on silicon-silicon triple bonding are investigated using density functional theory. It is predicted that Ar*Si=-SiAr* is very stable to isomerization and dimerization.
