Abstract

(Z, Z)-1-pentamethyldisilanyl-4-methoxy-1, 3-butadiene (5) in 37% yield. 4 Our hope was that thermal rearrangement of 5 to silene 6 would be followed by a elimination of trimethylmethoxysilane to produce carbene 7 which would cyclize to the desired silole 3. However, flow pyrolysis of 5 (760 OC at Torr) afforded in 52% yield a product which resulted from the loss of the elements of tetramethyl~ ilane~ from 5. This product was identified as ...
