Synthetic methods and reactions. 135. Single-step reductive isomerization of unsaturated polycyclics to C4n+6H4n+12 diamondoid cage hydrocarbons with sodium borohydride/triflic acid
Triplet lifetimes of cyclic olefins and dienes measured by pulseradiolysis are dependent on the ring size which affects the most stable conformation of the triplet. In the case of cyclic nonconjugated dienes, an intramolecular biradical formation is an important decay process when the reaction is sterically allowed.
