Berry exchange coordinate geometry in 3-methyl-2-hydroxycyclopenten-1-one tin esters

Synthesis and antitumor activity of a new mixed-ligand complex di-n-butyl-(4-chlorobenzohydroxamato)tin(IV) chloride

“…The similar geometry was demonstrated in the single crystal structure of 3-methyl-2-oxo-cyclopentanen-1-onechlorodiphenyltin [21]. Moreover, the similar bond lengths between tin(IV) and coordinated atoms are comparable to this reported compound [21]. The selected bond distances and bond angles are listed in Table 1.…”

“…The O(1), C(8) and C (12) are approximately in an equatorial plane with tin(IV) center, the mean deviation from the plane is 0.0515 Å and the O(2) and Cl(1) are in axial positions [O(2)-Sn(1)-Cl(1) 155.71(6)°]. The similar geometry was demonstrated in the single crystal structure of 3-methyl-2-oxo-cyclopentanen-1-onechlorodiphenyltin [21]. Moreover, the similar bond lengths between tin(IV) and coordinated atoms are comparable to this reported compound [21].…”

Triphenyl lead, tin and germanium coordination compounds derived from 9H-3-thia-1,4a,9-triaza-fluorene-2,4-dithione

“…We are currently investigating the chemistry of organometallic compounds of the group 14 elements [1,2] and particularly those coordinated to planar and aromatic molecules [3][4][5][6][7][8]. These ligands and the metal atoms provide hypervalent metal atoms and versatile coordination modes.…”

Cyclopentanone Derivatives from 5‐Hydroxymethylfurfural via 1‐Hydroxyhexane‐2,5‐dione as Intermediate

“…[8,15] MCP is ak nown flavor ingredient in roastedc offee and maple syrup, and is widely used in the food industry.I ta lso finds use as ap recursor for the biosynthesis of antibiotics, [16] as af ragrance in perfumery, [17] and as ligand in metal complexes. [18] Severalr outes towards MCP have been previously reported, starting from isoprene, [19] 2-keto-glutaric acid, [20] dimethyl adipate, [21] or 1-acetoxy3-buten-2-one. [22] We report the efficient synthesis of MCP startingf rom biomass-derived HMF in at wo-step process, involving HHD as an intermediate.…”
