GENERATION AND REARRANGEMENT OF A 1-NORBORNENE IN PYROLYSIS OF 1-SILA-OXYNORBORNANES
Barton, Thomas J.,Yeh Ming-Hsiung
, p. 6421 - 6424 (2007/10/02)
Gas phase pyrolysis of 1-sila-2-oxynorbornenes yields a nortricyclene which is proposed to arise from a β-elimination to form a 1-norbornene, which isomerizes to a 2-norbornacylidene which undergoes γ-CH insertion.
