Useful Synthetic Routes to Pure exo-5-Vinyl-2-norbornene and endo-5-Vinyl-2-norbornene

Hydroboration of 5-vinyl-2-norbornene (1) with 9-BBN mainly affords 5-(2-hydroxyethyl)-2- norbornene (2).The iodo ether cyclization of 2 can convert only endo-5-(2-hydroxyethyl)-2-norbornene (2b) to iodo ether 10, followed by reductive elimination and subsequent dehydration to furnish endo-5-vinyl-2-norbornene (1b) which has not been isolated in pure form.Meanwhile, unreacted exo-5-(2-hydroxyethyl)-2-norbornene (2a) produces exo-5-vinyl-2-norbornene (1a) via dehydration.

(ENDO)-5-(2-HALOETHYL)-2-NORBORNENE. A NEW RADICAL PROBE.

(endo)-5-(2-haloethyl)-2-norbornenes have been synthesized, and their corresponding radicals generated by reaction with sodium, magnesium, sodium naphthalenide and tri-n-butyltin hydride in the presence of AIBN to produce both straight chain and cyclized
