Abstract: Abstract This paper reports the synthesis of six potential catalyst precursors for hydrocracking reactions for vacuum residue refinement. New group 6 transition metal complexes, (LM(CO)3) (M = Mo or W, L1 = 3-phenyl-1-propyne, L2 = 4-phenyl-1-butyne, and L3 = 5-phenyl-1-pentyne) were prepared by simply… read more here.

Abstract: We report on the reactivity of a boryloxy-functionalized phosphaalkyne, [B]OCP ([B] = N,N′-bis(2,6-diisopropylphenyl)-2,3-dihydro-1H-1,3,2-diazaboryl), toward a series of tungsten(0) reagents to afford the novel complex W(η2-PCO[B])3(CO). As with related organometallic complexes of alkynes, the C3v symmetry… read more here.
