methyldichlorosilylcyclopentadiene show the presence of all three isomeric forms equilibrated through a prototropicrearrangement. The saturation transfer technique applied to the 5-isomer demonstrates this to undergo a fast metallotropic rearrangement. The signals are assigned to isomers or nuclei by double resonance. The spectrum of the main vinylic isomer has been analysed completely including the signs
