Hexakis (2, 6-dimethylphenyl) cyclotrisilane (1) l represents the first and thus far only compound that incorporates the silicon three-membered ring system. While the strain imposed upon this small ring is clearly and uniquely manifested in its chemical behavior, the full aryl substitution in 1 causes significant perturbation of the electronic structure intrinsic to the cyclotrisilane system2 With the purpose of eliminating this complication, the synthesis ...
