Three complexes of the general formula M{CpFe(η5‐C5H4CH=N–N=C(S)NH2}2 [where M = NiII (2a), PdII (2b) and ZnII (2c)] were synthesized with formylferrocene thiosemicarbazone (1) as a bidentate ligand. All compounds were characterized using conventional spectroscopic and analytical techniques (infrared, 1H and 13C NMR, mass spectrometry and elemental analysis). The molecular structure of 2b was confirmed by single‐crystal X‐ray analysis. To study the photocatalytic activity of the new complexes (2a–c), methylene blue (MB) was selected as a model pollutant. After 180 min, the degradation efficiency of MB reached 87% for 2a, 76% for 2b and 85% for 2c, and all complexes showed a higher photocatalytic activity than the formylferrocene thiosemicarbazone free ligand 1. Theoretical studies were used to characterize the geometry and electronic structure of the compounds and to provide a rational explanation for the measured photocatalytic activity.

In the research of new compounds with multifunctional applications, heterobinuclear palladium (II) complexes based on organometallic dithiocarbazates (DTCZs) have been isolated. The organometallic DTCZ ligands of the general formula [{(η5‐C5H4)‐CH=NNHC(S)SCH3}]MLn [MLn = Re (CO)3 (2a); Mn (CO)3 (2b); FeCp (2c)] were prepared by the reaction between formyl organometallic precursors (1a−c) with S‐methyldithiocarbazate. Subsequently, a two‐step reaction of 2a−c with: (i) K2[PdCl4] and (ii) PPh3 yielded heterobinuclear complexes [Pd{MLn(η5‐C5H4)‐CH=NNHC(S)SCH3}–(Cl)(PPh3)] [MLn = Re (CO)3 (3a); Mn (CO)3 (3b); FeCp (3c)]. All compounds were characterized by conventional spectroscopic techniques (infrared spectroscopy, nuclear magnetic resonance spectroscopy, mass spectrometry and elemental analysis). In addition, the molecular structures of 2a, 2c and 3c were determined by single‐crystal X‐ray diffraction. The new palladium (II) complexes (3a−c) were evaluated as antiproliferative agents against non‐small cell lung cancer cells (H1299 cells). Complexes 3a and 3b containing cyrhetrenyl‐ and cymantrenyl‐DTCZ ligands, respectively, were more active than their ferrocenyl analogue 3c. The activity was associated with the electron‐withdrawing properties of the (η5‐C5H4)M (CO)3 moieties and their better lipophilicity than that of the ferrocenyl analogue. In addition, we studied the capacity of metalloligands (2a−c) and palladium (II) complexes (3a−c) to remove methylene blue in water under UV–visible light irradiation. The results established that the complexes showed moderate efficiency and were less active than their corresponding free ligands.

The synthesis and characterization of the novel ferrocenyl sulfonyl hydrazide [Fe(η5-C5H5){(η5-C5H4)-S(O)2-NH-NH2}] (2) is reported. Additional studies on its reactivity in front of acetone or the ferrocenyl-, cyrhetrenyl- or cymantrenyl- aldehydes...

El presente manual se basa en la experiencia de investigación realizada entre los años 2018 y 2021 en el marco del proyecto FIBN N° 024/2017 “Exploración de métodos silvícolas, no silvícolas y de recolección sustentables para la producción de Hongos Silvestres Comestibles en bosque templado” financiado por el Fondo de Investigación de Bosque Nativo de Conaf y ejecutado en la comuna de Panguipulli, región de Los Ríos. Se proponen principios y criterios para la recolección sustentable de las especies loyo, changles, gargal y diweñe basados en el conocimiento local y en la información cuantitativa y cualitativa analizada en la investigación de estos cuatro años. También se comparte la experiencia de haber iniciado técnicas silvícolas y no silvícolas para mejorar la fructificación de las especies de HSC loyo, changles, gargal y diweñe, en su hábitat natural.

Los hongos han sido fundamentales para la evolución de la vida tal como hoy existe. Dentro de toda la diversidad de hongos que viven en la tierra hay un grupo que produce callampas o setas sobre el suelo, siendo varias de ellas comestibles. El presente documento sistematiza los antecedentes técnicos sobre distintas especies de HSC, además de plasmar los avances en la investigación sobre métodos de recolección sustentable y técnicas de propagación y cultivo. La recolección de HSC es una actividad ancestral realizada por el pueblo mapuche y otros pueblos originarios que habitaron Chile siglos atrás, el conocimiento traspasado de generación en generación ocupa una parte primordial en este documento.
