With the exception of PH2 (vs. NH2) all second row substituents, Na, MgH, A1H2, SiH3, SH and Qstabilize methyl cations more effectively than their first row counterparts. The effect of PH2, SH, and Cl substituents on the stability of methyl cations have been compared with NH2, OH, and F.le3 The same

The entire set of methyl anions, XCH,, substituted by first-row substituents, Li, BeH, BH2, CH3, NH2, OH, and F, was examined a t various ab initio levels. Diffuse orbital-augmented basis sets, such as 4-31+G and 6-31+~\*, are needed to describe the energies of these anions adequately. Estimates of
