)n(CO)9−2n [PP = (PPh3)2, Cp’ = Cp, n = 1, 5; PP = dppe, Cp′ = Cp∗, n = 1, 6; 0, 7] are also described. Syntheses of bis-cluster complexesCo3(μ-dppm)(CO)7}2(μ-Cx) (x = 14, 12; 16, 9; 18, 11; 26, 10) – the latter being the longest cluster-capped Cx chains so far described – and the mercury-bridged compounds Hg(CC)xC[Co3(μ-dppm)(CO)7]}2 (x = 1, 13; 2, 14) are reported. The molecular structures of
emergence of resistance against existing antileishmanial drugs necessitates the search for new classes of antileishmanial compounds. Herein a series of structurally diverse ferrocenylquinolines have been synthesized and evaluated for in vitro antileishmanial activity against Leishmania donovani using the MTT assay. Thirteen (M2-M14) substituted ferrocenylquinoline congeners possessing triazole rings were

An efficient cross coupling of alkynes with alkynyl and alkenyl halides catalysed by a Ni–Cu system without any ligand leading to the synthesis of a series of functionalised 1,3-di-ynes and en-ynes has been achieved.

A series of alkynyl-tricobalt carbonyl clusters, Co3(μ3-CnR)(μ-dppm)(CO)7 [R = But, Ph, C6H4I, C6H4CCPh, SiMe3, Fc, Au(PPh3)] containing three, five or seven carbons in the chain, have been prepared by elimination of phosphine–gold(I) halides in reactions between Co3(μ3-CBr)(μ-dppm)(CO)7 and Au(CCR)(PPh3) or between Co3μ3-CCCAu(PR3)} (μ-dppm)(CO)7 (R = Ph, tol) and ICCR′ (R′ = SiMe3, Fc). The use
