“…Milosavljević et al described the environmentally friendly methodology involving the use of oxidants (sodium percarbonate + EDTA system was most efficient, but also H 2 O 2 and air were tested) and solvent recycling [71]. Other modifications of reaction conditions for the reaction of amines with CS 2 have been proposed, including green variants: the use of solar energy [72], microwaves [73,74], ionic liquid media [75,76].…”

For almost 20 years, thioureas have been experiencing a renaissance of interest with the emerged development of asymmetric organocatalysts. Due to their relatively high acidity and strong hydrogen bond donor capability, they differ significantly from ureas and offer, appropriately modified, great potential as organocatalysts, chelators, drug candidates, etc. The review focuses on the family of chiral thioureas, presenting an overview of the current state of knowledge on their synthesis and selected applications in stereoselective synthesis and drug development.

“…En el caso de aminas aromáticas con grupos electrodonadores como la 4-isopropilanilina o la 4-metoxianilina el producto tiourea fue obtenido con rendimientos mayores al 95%, mientras que si emplean aminas aromáticas con grupos electroatractores tales como la 4-nitroanilina no son buenos sustratos para la reacción y generan productos con bajos rendimientos. En este mismo sentido, se desarrolló la síntesis de tioureas a partir de aminas primarias y disulfuro de carbono empleando agua como disolvente en presencia de energía solar (Kumavat, 2013) (figura 14).…”

“…blando y duro, respectivamente) proveen múltiples posibilidades de enlace (Henderson, 2002). Comercialmente, las tioureas se utilizan en la fabricación de plásticos, textiles, colorantes y películas fotográficas (Schroeder, 1955) En la actualidad, las tioureas son compuestos de gran importancia en química medicinal debido a su actividad biológica como medicamentos antituberculosos (Karakuş, 2002), antiinflamatorios (Ranise, 2003), antimicrobianos (Cunha et al 2007), antiarrítmicos (Chalina, 1998), fungicidas, herbicidas y rodenticidas (Kumavat, 2013). Algunas aplicaciones de estos compuestos tiourea se resumen en la figura 2.…”

Las tioureas son compuestos orgánicos cuya síntesis y reactividad ha sido extensamente estudiada en muchos campos de la química, debido a las diversas aplicaciones biológicas y medicinales que estos compuestos poseen. Los métodos más comunes para sintetizar tioureas involucran reactivos como el tiofosgeno, con alto grado de toxicidad, o los isotiocianatos que son difíciles de preparar, pero además se requieren condiciones drásticas de reacción para algunas veces obtener productos con bajos rendimientos. Por lo que cada día se buscan nuevas alternativas en la síntesis de tioureas que permitan obtenerlas de manera rápida, económica y que además se minimice el uso de condiciones drásticas de reacción, catalizadores y disolventes que sean inflamables y contaminen el medio ambiente.

Abstract. We have designed and synthesized an efficient and novel photosensitive two small organic molecules with different lengths of methine units, cyano groups as the electron acceptor units, and amino groups as the electron donor units. Compound 1 was synthesized from benzaldehyde, malononitrile and hydrazine hydrate and benzaldehyde whereas compound 2 was synthesized from benzaldehyde, Dimedone and hydrazine hydrate and their thermal, phovoltaic and surface properties were studied. Then these small molecules were utilized for development of organic solar cells in FTO: ZnO: Organic compound: Electrolyte: Pt electrode pattern.
