Relative rates kax and keq of addition reactions to title compounds have been measured in eight different reaction conditions. The effect of changing the axial substituent in the position 3 and 4 to the carbonyl group from -H to -Me and -CO2R is described. Data show that stereochemical product ratios changes originate sometimes from uneven increase (or decrease) of both kax and keq and sometimes from
