- Transmission of Polar Substituent Effects Through the Bicyclooctane Ring System as Monitored by NMR Shifts: a 13C NMR Study of 4-Substituted-1-methylbicyclooctanes
-
Carbon-13 substituent chemical shifts (SCS) are reported for the methyl group of a series of 4-substituted 1-methylbicyclooctanes covering a wide range of electronic substituent effects.Unlike the 13C SCS of the α-carbon centre in various unsaturat
