Scheme 3. Fragmentation route for an asymmetric (R, OH)-PDMS (with R=Me, Et) adducted with anion A− (with A=HCOO, CH3COO). (A) Abstraction of the acidic hydrogen from the hydroxy termination by A− to yield an− product ions. (B) Intramolecular bond translocation to yield ln product ions. Additional bond translocations and/or elimination of cylic Dn neutral through a backbitting process would produce smaller congeners.
