The crystal structures of (3S,4aS,8aS)-2-[(2R,3S)-3-benzamido-2-benzo-yloxy-4-phenyl-but-yl]-N-tert-butyldeca-hydro-iso-quinoline-3-carboxamide, C38H47N3O4, (I), and (3S,4aS,8aS)-2-[(2R,3S)-3-(2,5-di-chloro-benzamido)-2-(2,5-di-chloro-benzo-yloxy)-4-phenyl-but-yl]-N-tert-butyldeca-hydro-iso-quinoline-3-carboxamide, C38H43Cl4N3O4, (II), are described. Despite their chemical similarity, they adop...

The new cis-dioxomolybdenum (VI) complexes [MoO2(L2)(H2O)] (2) and [MoO2(L3)(H2O)] (3) containing the tridentate hydrazone-based ligands (H2L2 = N'-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-methylbenzohydrazide H2L3 N'-(2-hydroxybenzylidene)-2-(hydroxyimino)propanehydrazide) have been synthesized characterized via IR, 1H 13C NMR spectroscopy, mass spectrometry, single crystal X-ray diffraction...

A four-electron-reduced ruthenium(ii) NADH-type complex, [Ru(bbnpH4)(CO)2Cl](PF6) (bbnpH4 = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(5,10-dihydrobenzo[b][1,5]naphthyridine)), has been successfully synthesized by mixing an NAD+-type ligand, bbnp (bbnp = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(benzo[b][1,5]naphthyridine)), and [Ru(CO)2Cl2] under moderate water-gas-shift reaction conditions, wh...

Ammonolysis of fatty acids to the corresponding fatty acid amides is efficiently catalysed by Candida antartica lipase (Novozym 435). In the present paper lipase-catalysed synthesis of erucamide by ammonolysis of erucic acid and urea in organic solvent medium was studied and optimal conditions for fatty amides synthesis were established. In this process erucic acid gave 88.74 % pure erucamide a...

Abstract The Staudinger reaction of 2,5‐bis((di‐ tert ‐butylphosphaneyl)methyl)‐1 H ‐pyrrole ( t Bu PNP)H; PNP=C 4 2 N‐2,5‐CH P ) with equiv. Me 3 SiN cleanly furnishes 1,1′‐((1 ‐pyrrole‐2,5‐diyl)bis(methylene))bis(1,1‐di‐ ‐butyl‐ N ‐(trimethylsilyl)‐λ 5 ‐phosphanimine) 1 ; (NPNPN)H, NPNPN=C NSiMe in excellent yield. Pyrrole is easily deprotonated by alkali metal amides, [MN(SiMe ] (M=Li, Na, K...

The title compound, [Zr(C(5)H(5))(2)(C(4)H(9)N)(C(5)H(5)N)], was obtained from the reaction of (C(5)H(5))(2)Zr(py)(η(2)-Me(3)SiC(2)SiMe(3)) (py is pyridine) and (t)BuN=C=N(t)Bu alongside the formation of (C(5)H(5))(2)Zr(CN(t)Bu)(η(2)-Me(3)SiC(2)SiMe(3)). The zirconium atom is coordinated in a distorted tetra-hedral geometry by two cyclo-penta-dienyl ligands, a pyridine ligand, and a tert-butyl-...

The crystal structures of the title compounds, 1,3-di-tert-butyl-2,3-dihydro-1H-1,3,2-diazasilol-2-ylidene, C10H20N2Si (1) and 1,3-di-tert-butyl-2,2-dichloro-1,3-diaza-2-sila-4-cyclopentene, C10H20N2SiCl2 (3) were solved and are reported. Compound (1) crystallized in space group P mmn and each molecule has a mirror plane, which bisects the C-C backbone of the N-C-C-N framework. Compound (1) was...
