Ferrocene-based compounds are powerful asymmetric ligands usable for chemical catalysis. We present the synthesis of six new homochiral diferroceno cycles potentially useful as P,O-, P,N- or P,S-ligands. Due to the stereoconservative nature of the SN1 reaction at carbons adjacent to ferrocene units, we obtained a single diastereomer of the 8-membered diferroceno[c,f]heterophosphocines in all cases.
