Importance The protein-based SARS-CoV-2 vaccines FINLAY-FR-2 (Soberana 02) and FINLAY-FR-1A Plus) showed good safety immunogenicity in phase 1 2 trials, but the clinical efficacy of vaccine remains unknown. Objective To evaluate a 2-dose regimen (cohort 1) 3-dose with 2) Iranian adults. Design, Setting, Participants A multicenter, randomized, double-blind, placebo-controlled, 3 trial was conducted at 6 cities cohort 2. included individuals aged 18 to 80 years without uncontrolled...
Abstract A novel Ni/Cu/Fe nanocatalyst was prepared via a three‐step procedure for the 3 ‐coupling reaction of an aldehyde, amine, and terminal alkyne to synthesize corresponding propargylamine. Oleic acid used in second step avoid aggregation CuFe 2 O 4 nanoparticles. The NiO/OA‐CuFe (Ni/Cu/Fe) characterized using X‐ray diffraction (XRD), scanning electron microscopy/wavelength dispersive (SEM/WDX), particle size analyzer, fourier transform infrared (FT‐IR) atomic absorption spectroscopy...

A magnetically recoverable heterogeneous catalyst was synthesized by immobilization of Pd on the surface oleic acid coated Fe3O4 nanoparticle. This used for Heck coupling reaction styrene with various aryl halides in aqueous media. The /product separation could be easily achieved external magnetic field. Keywords: Aryl halides, heck reaction, catalyst, nanoparticles, acid, palladium nanoparticles.

Abstract The quinaldyl ketone, 4‐phenyl‐3‐(quinolin‐2‐yl)‐butan‐2‐one was prepared by two methods: (a) benzylation of 1‐(1 H ‐quinolin‐2‐ylidene)propan‐2‐one in the presence sodium hydride dimethylformamide and (b) benzylative demethoxycarbonylation methyl 2‐(1 ‐quinolin‐2‐ylidene)‐3‐oxobutanoate lithium bromide hexamethylphosphoramide at 135°. In absence acid, compound exists exclusively tautomeric form, 4‐phenyl‐3‐(1 ‐quinolin‐2‐ylidene)butan‐2‐one.
Abstract In analogy to the reaction of dimethyl malonate (I) or dimedone (IV) with diethyl azodicarboxylate (II) give N‐C linked products (III) (V), ketones (VI) are coupled triazolinedione (VII) in presence trifluoroacetic acid, yielding α‐urazolyl (VIII).
Abstract The catalyst can be easily recovered by external magnetic field and reused several times without significant loss of activity.
Abstract Increasing the electron withdrawing nature of substituents at aryl halides (I) and (IV) significantly decreases yield reaction probably due to a competitive dehalogenation reaction.
