The multifunctional ligand bis(diphenylphosphino)-1,9-nonadiyne (1; abbreviated as dpndy) has beenprepared by sequential treatment of HC
C(CH2)5CCH with BuLi and PPh2Cl. Compound 1 reactswith W(CO)4(NCMe)2 to give W(CO)4(
2-dpndy) (2), while the reaction of 1 and W(CO)3(Me3tach)(Me3tach = 1,3,5-trimethyl-1,3,5-triazacyclohexane) produces W(CO)3(2-dpndy)(1-dpndy) (3), [W(CO)3(2-dpndy)]2(
,2-dpndy) (4), and the paddle-wheel complex [W(CO)3]2(,2-dpndy)3 (5). Further treatmentof W(CO)3(Me3tach) with 3 generates the tripodal compound W(CO)3[(,2-dpndy)W(CO)3(2-dpndy)]3(6). The molecular structures of 2 and 5 have been determined by an X-ray diffraction study.
