Synthesis, Spectroscopic and Theoretical Studies of Ruthenafuran and Osmafuran Prepared by Activation of Ynone in Alcohol

Abstract: Ruthenafuran and osmafuran monocationic complexes [Ru([14]aneS4)(C ∧ O)] + or [M(bpy) 2 (C ∧ O)] + (C ∧ O = anionic bidentate chelate [C(OR)CHC(Ph)O] − ; [14]aneS4 = 1,4,8,11-tetrathiacyclotetradecane; M = Ru, Os; bpy = 2,2′-bipyridine) have been prepared from reactions between phenylynone HCC(CO)Ph and [Ru ([14]aneS4)Cl 2 ] or [M-(bpy) 2 Cl 2 ] in alcoholic solvents ROH. The formation of metal− vinylidene intermediate, followed by nucleophilic attack by RO − , and carbonyl group coordination to the metal ce… Show more

“…The first successful synthesis of metal-indolizine complexes 1a-1c was accomplished by reactionb etween the Ru II precursor [Ru( [9]aneS3)(bpy)(H 2 O)] 2 + and pyridine-substituted propargylic alcohols HCCC(OH)(2-py)R in water (Scheme 2a; [9]aneS3 = 1,4,7-trithiacyclononane). [4] It should be pointed out that the term "indolizine" here actually refers to "1,1-disubstituted 1H-indolizinium-2-yl" zwitterion.…”

“…The first metalated indolizinonec omplexes 3-5 were prepared from reactions between [Ru( [9]aneS3)(bpy)(H 2 O)] 2 + or [Ru( [14]aneS4)Cl 2 ]a nd pyridine-substituted ynones RCC(C= O)(2-py) (Scheme4;t he term "indolizinone" here referst o" 3monosubstituted 1-indolizinonium-2-yl" zwitterion). [7] As shown in the crystal structures,t he ynones cycloisomerize into indolizinones and behavea sm onodentate ligands coordinating through the C-2 ( Figure 2).…”
