Summarv : The transition state structures for addition of LiH to 1, 2, and 3 are computed and analyzed at MP2/6-3lG(d)//HF/6\_3lG(d). Three factors are found to be important for the relative energies of the transition state structures: (i) the conformational energy of the aldehyde; (ii) the interac
