Related tungsten complexes have been prepared by diverse routes. Phosphine, phosphite, and isonitrile W(CO)2(RC=CR)LI2 complexes form from W(CO)4LI2 and alkyne [Eq. (3)] (44). Parent acetylene (HC2H) complexes were isolated as m-dicarbonyl derivatives for L equal to PMe3 or AsMe3, and both cis- and Pms-dicarbonyl derivatives were characterized with phenylacetylene in the coordination sphere. 

Bis-nitrogen donor ligand-substituted alkylidyne complexes such as 78 were found to be good alternatives as starting materials to the thermally labile tetracarbonyl complexes 44). Substitution of one pyridine ligand in the bispyridine-substituted complexes 78 occurs in the presence of excess chloride [Eq. (64)] 103). The anionic complexes 79 are stable in the presence of excess chloride but are too labile to be isolated in pure form. These complexes were used in the synthesis of stable alkylidyne alkene tungsten complexes [Eq. (180), Section IV,G]. With phosphines both pyridine ligands in 78 are substituted [Eq. (65)] 44). For PMej the reaction of the tetracarbonyl complex W(CPh)Br(CO)4 had previously been shown to... 

Reaction of the tungsten complex 167 with diphenylphosphine at elevated temperatures affords complex 168 [Eq. (140)] (76i). The same compound could be obtained by sequential addition of LiPPh2 and NH4Br. Formation of this product is surprising considering the ease with which some phospines induce carbyne-carbonyl coupling in complex 167 (see Section IV,F). The by-product 169 could possibly be derived from an intermediate ketenyl complex. Protonation of complex 168 in acetonitrile occurs at the former carbyne carbon to give the phosphine complex 170.
