A series of ethynylated silanes, including tetraethynylsilane was treated with tetraphenylcyclopentadienone at 300 8C under microwave irradiation to give the aromatized Diels-Alder adducts as sterically encumbered mini-dendrimers with up to 20 benzene rings. The sterically most congested adducts display red-shifted emission through intramolecular p-p interactions in the excited state.
Unprecedented cesium and potassium fluorides catalyzed trialkylsilylation and tributylstannylation of terminal alkynes with trifluoromethyl-trialkylsilanes and -tributylstannane

Cesium and potassium fluorides promoted trialkylsilylation and tributylstannylation of terminal alkynes with trifluoromethyl-trialkylsilanes and -tributylstannane were found to give 1-silyl- and 1-tributylatannyl-alkynes in high yield. The present reactions are applicable to 1-alkynes having a wide range of functional groups such as acetal, iodo, silyl, amino, amido and carbonyl (except for aldehyde) groups.
