Combinatorial Enumeration of Homo and Hetero-Polysubtituted [4.2]-Paracyclophane Derivatives

Robert Martin Nemba, Patouossaissofa and A. Emadak

combinatorial enumeration using the unit-subduced-cycle index approach with symmetry chararacterisation is carried out for homo- and hetero-polysubstituted [4.2]-paracyclophane derivatives symbolized respectively by the empirical formulas ϕ 2 C6 Hq0 Xq1 and ϕ 2 C6 Hq0 Xq1 Y q2 where X and Y are a non-isomerisable ligands and where the greek symbol ϕ represents the hydrogen depleted benzene ring
