Starting from the previously reported 5-HT 7 receptor agents 4-7 with N-(1,2,3,4-tetrahydronaphthalen-1-yl)-4-aryl-1-piperazinehexanamide structure, the 1-(2-methylthiophenyl)-, 1-(2-diphenyl)-, 1-(2-isopropylphenyl)-, and 1-(2-methoxyphenyl)piperazine derivatives 8-31 were designed with the primary aim to obtain new compounds endowed with suitable physicochemical properties for rapid and exten...

In the title compound, [FePt(C(5)H(5))(C(24)H(19)NP)Cl(2)]·0.5CH(2)Cl(2), the Pt(II) atom adopts a distorted square-planar geometry defined by one P atom and one N atom from the bidentate [2-(diphenyl-phosphino)phenyl-imino-meth-yl]ferro-cene ligand and two Cl atoms. Two disordered dichloro-methane solvent mol-ecules are each 0.25-occupied on a twofold rotation axis.

There are two independent Pd(II) complex mol-ecules in the asymmetric unit of the title compound, [PdCl(2){Fe(C(5)H(5))(C(24)H(19)NP)}]·0.5CH(2)Cl(2). One ferrocenyl ring of one complex mol-ecule is disordered over two sites with half-occupancy for each component. Both Pd(II) cations adopt a distorted square-planar coordination geometry with a bidentate [2-(diphenyl-phosphino)phenyl-imino-meth-...

New podand-type fluoroionophores having two pyrene moieties: 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfide (3), 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfoxide (4), and 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfone (5), have been synthesized by connecting two 1-pyrenecarbonylmethyl groups with the two hydroxy groups of 2,2´-dihydroxydiphenyl sulfide, sulfoxide, and sulfone, respectively. Their com...

In the title compound, [Co(C(4)H(9))(C(14)H(11)N(2)O(2))(2)(C(5)H(5)N)], the Co(III) atom is coordinated by a butyl group, a nitro-gen-bonded pyridine and two N,N'-bidentate diphenyl-glyoximate ligands in a distorted octa-hedral geometry. The crystal structure features two short O-H⋯O bridges between the two chelating anions, with O⋯O distances less than 2.5 Å.

Abstract The oxidation of various non‐S‐oxidized 4 H ‐1,2,6‐thiadiazines with N 2 O , meta ‐chloroperbenzoic acid ( m ‐CPBA), Oxone, [bis(trifluoroacetoxy)iodo]benzene (PIFA) and phenyliodine (III) diacetate (PIDA) is reported. Six 3,5‐diamino‐4 ‐1,2,6‐thiadiazin‐4‐ones were oxidized to the corresponding sulfones (67–95 % yields) most efficiently using PIFA (3 equiv.). A 3,5‐diphenylthio analog...

The alkoxycarbonylation of trimethylsilylacetylene has been studied in order to develop an atom economic sustainable synthesis 2‐(trimethylsilyl)acrylates, a family valuable intermediates. Pd(OAc) 2 combination with CH 3 SO H and diphenyl‐(pyridin‐2‐yl)phosphine or diphenyl‐(6‐methyl‐pyridin‐2‐yl)phosphine is active catalyst for the reaction affording mixtures sought 2‐(trimethylsilyl)acrylate ...
