A series of quadruply bonded dimolybdenum compounds of form Mo(2)(EE'CC≡CPh)(4) (EE' = {NPh}(2), Mo(2)NN; {NPh}O, Mo(2)NO;{NPh}S, Mo(2)NS; OO, Mo(2)OO) have been synthesised by ligand exchange reactions of Mo(2)(O(2)CCH(3))(4) with the acid or alkali metal salt of {PhC≡CCEE'}(-). The compounds Mo(2)NO, Mo(2)NS and Mo(2)OO were structurally characterised by single crystal X-ray crystallography. ...

In this paper we demonstrate a method of synthesizing oligoenes of diisopropyldipropargylmalonate, [CH2][bx][CH2] (x ) 2, 3, 4, 5), in which the “b” repeat unit is identical to the five-membered ring formed in a tail-to-tail cyclopolymerization of diisopropyldipropargylmalonate, and methylene groups are capping the ends. For example, a “degenerate” metathesis reaction between the “monomer”, [CH...

This study utilized Swietenia mahagoni bark–a wood processing industry waste, for the preparation of activated carbon, and then investigated for the removal of methyl orange (MO) dye by the Swietenia mahagoni bark activated carbon (SMBAC). The effect of pH (3–10), adsorbent dose (1–30 g/L), initial MO dye concentration (10–100 mg/L), and contact time (1–240 min) were evaluated...
