The synthesis and reactivity of binuclear μ-hydrocarbyl complexes of some transition metals
The new μ-(l,n)-alkanediyl compounds [(ƞ⁵-C₅R₄Me)Fe(CO)₂ ]₂{μ-(CH₂)n}, (R = H, n = 3 -10 and R =Me, n =3 - 6), [Mn(CO)₅]₂{μ-(CH₂)n} (M = Mn, n = 4-6 and M = Re, n= 3 and 4) have been prepared using essentially two synthetic routes. Thus the iron compounds were synthesized by the reaction of …

Studies in the synthesis of 4, 5-disubu/stituted phenanthrenes /|nK. Ramakrishnan. -- 260 St. Catharines, Ont. : [s. n.],
… nucleus . It has been found t hat the unbridged structures are not preferred if the compound is capable of isomerising to a bridged form . We have explained this phenomenon in t erms of the stereochemistry of t he 4 and 5 positions of the phenanthrene nucleus as well as the geometry of …

Studies on the synthesis and the transport properties of organic materials
… 15-20°C higher than those for their biphenyl-bridged analogues, and are 0.11-0.14 V more easily oxidized. The hole mobilities of the three fluorene derivatives (blended with polystyrene) have been measured by the time-of-flight technique and are lower than the corresponding biphenyl-bridged …

Alkane Elimination Reactions between Transition Metal Hydrides and Rare-Earth Alkyls
… (0.5-2.0 equiv [Cp*RuH2]2) the cluster compounds were obtained selectively. Solid state structures of both compounds could be established by XRD analyses. The isostructural compounds feature four Ln-Ru intramolecular distances of which one is significantly shorter than the three others. …
