The syntheses and spectroscopic parameters of the new tertiary phosphane ligands ( p ‐MeOC 6 H 4 )( o ‐MeOC 6 H 4 ) 2 P ( 1 ), ( p ‐MeOC 6 H 4 )( o ‐MeSC 6 H 4 ) 2 P ( 2 ), ( p ‐MeSC 6 H 4 )( o ‐MeSC 6 H 4 ) 2 P ( 3 ), ( p ‐MeSC 6 H 4 )( o ‐MeOC 6 H 4 ) 2 P ( 4 ), ( p ‐MeOC 6 H 4 )( o ‐NC 5 H 4 ) 2 P ( 5 ), and ( p ‐MeSC 6 H 4 )( o ‐NC 5 H 4 ) 2 P ( 6 ) are reported. Single‐crystal X‐ray structures of all the compounds ( 1–6 ) have been determined. The dependence of the 31 P‐NMR chemical shifts on the substituent groups of the phosphanes is discussed.
