The pattern of bond cleavage in the hydrogenolysis of aziridines generally follows that observed with cyclopropanes. Alkyl substituted aziridines are cleaved at the most accessible C-N bond. This provides a good route to the production of molecules having a primary amine group on a tertiary carbon (Eqn. 20.48). ... 

These can be made by various routes, including hydrogenolysis of Ln-C bonds thermolysis of alkyls and substitution of halide. Thus hydrogenolysis of the dimeric methyl-bridge cyclopentadienyl complexes (Ln, e.g., Y, Er, Yb, Lu) in THE affords [Cp2Ln(thf)(/u,-H)]2 ...
