    • In the absence of alkyne, silylborane 4a slowly reacted at room temperature in the presence of the Pd/PPh3 complex (10 mol , resulting in the formation of 11a (84% yield after 48 h) with organosilicon compounds, which exhibited 1H NMR signals in the region of -1.0 to 0.6 ppm. Although they were hardly identifiable, dodecamethylcyclohexasilane was detected by 1H NMR and GCMS analysis as a very minor <1, component
