| The Thermal Isomerization of a Tetrahydro-2,3-disilanaphthalene into a 1,2-Disilacyclobutane -The Conversion of a Formal Silene [2+4] Cyclodimer into the [2+2] Cycloadduct | | | | Abstract
| 1,2,3,8a-Tetrahydro-1 -mesityl-5,7,8a-trimethyl-2,2,3,3-tetrakis(trimethylsilyl)-2,3-disila-naphthalene (3), the formal [2+4] cyclodimer of the transient 2-mesityl-l,l-bis(trimethylsilyl)-silene (2), on thermal treatment gradually isomerizes to give a mixture of the [2+2] products (E)-and -predominantly -(Z)-3,4-dimesityl-1,1,2,2-tetrakis(trimethylsilyl)-l,2-disilacyclo-butane [(E/Z)-4], By prolonged heating or at higher temperatures both (E/Z)-3 and (Z)-4 are converted into (E)-4, the thermodynamically most stable head-to-head dimer of 2. Possible pathways of the isomerization processes are discussed. | | | |
