This thesis deals with sp carbon chain compounds bearing one or more terminal groups of the formula (5-C5Me5)Re(NO)(PAr3) (PAr3 = (3,5-(H3C-4-C6H4CH2CH2)2-C6H3)3P (1), (3,4-(H3C-4-C6H4CH2CH2)2C6H3)3P (2), and (3,4,5-(H3C-4-C6H4CH2CH2)2-C6H2)3P (3)). The syntheses of the new bulky phosphines or “superphosphines” 1-3 will be described. Other metal complexes and derivatives of 1-3 are prepared, and they are tested as ligands in metal catalyzed reactions. Chapter 1 describes the syntheses of the superphosphines 1 - 3. 1,2-dibromobenzene was nitrated in conc. HNO3 to give 1,2-dibromo-4-nitrobenzene. Reaction with p-tolylacetylene (7) under Sonogashira conditions (Pd(PPh3)4, CuI, NEt3) gave 3,4-(H3C-4-C6H4CH2CH2)2C6H3NO2 in 70% yield. The...
