The first 2‐phospha[3]ferrocenophanes containing stereogenic carbon atoms in the three‐atom bridge have been synthesised from phenylphosphane by stereospecific ring‐closing phosphanation reactions. Either α‐substituted 1,1′‐bis(hydroxymethyl)ferrocenes or the corresponding 2‐oxa‐[3]ferrocenophanes have been used as diastereomerically pure starting materials. The resolution of 1,2,3‐triphenyl[2]phosphaferrocenophane has been achieved by chromatographic separation of the diastereomeric adducts of a chiral cyclopalladate complex. The X‐ray crystal structures of two 2‐phospha[3]ferrocenophane‐borane complexes are also reported. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
