  摘要：

  4-Substituted 1-(4-fluoro- and 4-chlorophenyl)pyrrolidin-2-ones containing azole, oxadiazole, triazole, and triazine fragments have been synthesized, and the characterization of the obtained products is presented. The study compounds have been analyzed by elemental analysis, and the NMR, IR, MS techniques. The H-1/C-13 2D (HETCOR), APT (C-13) NMR methods, and molecular modeling (MM2) were used for structure elucidation in more complicated cases.

  The reaction between the equimolar amounts of cis-[PdCl2(CNR1)(2)] (R-1 = cyclohexyl (Cy) (1), tBu (2)) and the carbohydrazides (RCONHNH2)-C-2 (R-2 = Ph (5), 4-ClC6H4 (6), 3-NO2C6H4 (7), 4-NO2C6H4 (8), 4-CH3C6H4 (9), 3,4-(MeO)(2)C6H3 (10), naphth-1-yl (11), fur-2-yl (12), 4-NO2C6H4CH2 (13), Cy (14), 1-(4-fluorophenyl)-5-oxopyrrolidin-3-yi (15), (pyrrolidin-1-yl)C(0) (16)) proceeds in refluxing CHCl3 for ca. 4 h. A subsequent workup provided the amino-carbene species cis-[PdCl2C(NHNHC(O)R-2)=N(H)R-1}-(CNR1)] (18-33) in good to excellent (80-95%) isolated yields. The coupling of equimolar amounts of cis-[PdCl2(CNR1)(2)] (R-1 = Cy (1), tBu (2), 2,6-Me2C6H3 (XYI) (3), 2-Cl-6-MeC6H3 (4)) and PhSO2NHNH2 (17) occurs similarly and affords the aminocarbenes cis-[PdCl2C(NHNHS(O)(2)Ph)=N(H)R-1}(CNR1)] (34-37; 60-90%). Complexes 18-37 were characterized by elemental analyses (C, H, N), ESV+-MS, IR, and 1D (H-1, C-13H-1}) and 2D (H-1,H-1-COSY, H-1,C-13-HMQC, H-1,C-13-HSQC, HMBC) NMR spectroscopy, as well as by X-ray diffraction for three species (34, 37, and 38). The catalytic properties of 18-37 in Suzuki Miyaura cross-coupling in aqueous medium were evaluated, and 18-37 showed remarkable activity (0.001-0.01 mol % catalyst loading). The scope of the catalytic process covers sterically unhindered and sterically demanding aryl bromides and aryl iodides bearing donor and/or acceptor substituents and activated aryl chlorides. All organohalides reacted with a range of arylboronic acids at 80 degrees C within 2 h (100 degrees C and 3 h for the chlorides), providing target diaryis in yields up to 99% and with maximum TONs of 9.9 X 10(3) (for aryl iodides), 4.7 X 104 (for aryl bromides), and 9.2 X 10(3) (for aryl chlorides).

  Metal-mediated coupling of one isocyanide in cis-[PdCl2(CNR1)(2)] (R-1 = C6H11 (Cy) 1, tBu 2, 2,6-Me2C6H3 (Xyl) 3, 2-Cl-6-MeC6H3 4) and various carbohydrazides (RCONHNH2)-C-2 [R-2 = Ph 5, 4-ClC6H4 6, 3-NO2C6H4 7, 4-NO2C6H4 8, 4-CH3C6H4 9, 3,4-(MeO)(2)C6H3 10, naphth-1-yl 11, fur-2-yl 12, 4-NO2C6H4CH2 13, Cy 14, 1-(4-fluoropheny1)-5-oxopyrrolidine-3-yl 15, (pyrrolidin-1-yl)C(O) 16, 3-(3,5-di-tert-butyl-4-hydrox yphenyl)propane-1-yl 17, EtNHC(O) 18] or sulfohydrazides (RSO2NHNH2)-S-3 [R-3 = Ph 19, 4-MeC6H4 20] led to a series of (hydrazido)(amino)carbene complexes cis-[PdCl2(C) under bar (NHNHX)=N(H)R-1)(CNR1)1; X = COR2, SO2R3 (21-48, isolated yields 60-96%). All prepared species were characterized by elemental analyses (C, H, N), HR ESI+-MS, IR, H-1 and C-13H-1} NMR spectroscopy, and by a single-crystal X-ray diffraction for 38. Complexes 21-48 demonstrated excellent activity as catalysts in copper-free Sonogashira coupling of aryl iodides and a variety of aromatic terminal alkynes. Catalytic system runs in environmentally benign EtOH ensuring product yields of up to 75-96% and TONs of up to 10(4). Mechanism of the copper-free Sonogashira catalytic cycle involving 21-48 as catalysts was proposed upon identification of key intermediates using HRESI-mass. (C) 2015 Elsevier Inc.

  The reactions of 1-aryl-4-hydrazinocarbonyl-2-pyrrolidinones with 2,4-pentanedione and 2,5-hexanedione have been studied. It was found that heating the hydrazinocarbonyl compounds with 2,4-pentanedione gave 3,5-dimethylpyrazole compounds and with 2,5-hexanedione gave 1-substituted 2,5-dimethylpyrroles.
