In the gas phase, the (CH,),SiOSi(CH,),' and (CH,),Si'OSi(CH,)CH, ions were formed in the external source of a FT-ICR mass spectrometer by fragmentation of (CH,),SiOSi(CH,),". In the cell, the electrophilic center of these ions reacts with water to give product-ions which undergo, spontaneously or
Collisionally activated dissociation of deprotonated aromatic sulfonic acids in the gas phase causes rearrangement and fragmentation to produce the corresponding phenoxide ions. The mechanism for this reaction has been investigated and the results of this study favor initial intramolecular nucleophi
