Speicherung des labilen Silaethens Me2Si=C(SiMe3)2 mit Benzophenon [1] Storing of the Labile Silaethene Me2Si = C(SiMe3)2 with Benzophenone [1]

Silaethene Me2Si = C(SiMe3)2. Insertions, Cycloadditions, Kinetic Studies Benzophenone P h 2 C = 0 is able to "store" the silaethene Me2Si = C(SiMe3)2 (1). produced from Me 2SiX-CLi(SiMe 3) 2 (X = F. Br, Ph 2 P0 4 ) , under formation of a [2+4] cycloadduct (2b). At about 100 °C, 2b by way of 1 transfers into the [2+2] cycloadduct of 1 and P h 2 C = 0 (3b… CONTINUE READING
