CAS 80-70-6: 1,1,3,3-Tetrametilguanidina
Descripción:
1,1,3,3-Tetrametilguanidina (TMG) es un compuesto orgánico caracterizado por su estructura de guanidina, que presenta cuatro grupos metilo unidos a los átomos de nitrógeno. Es un líquido incoloro a amarillo pálido con un fuerte olor a amina. Se conoce que el TMG tiene una alta basicidad, lo que lo convierte en una base no nucleofílica efectiva en diversas reacciones orgánicas, particularmente en la síntesis de productos farmacéuticos y agroquímicos. Es soluble en agua y en muchos disolventes orgánicos, lo que mejora su utilidad en diversos procesos químicos. El TMG también es reconocido por su capacidad para estabilizar carbaniones y facilitar reacciones de desprotonación. Sin embargo, debe manejarse con cuidado debido a sus propiedades irritantes potenciales y la necesidad de medidas de seguridad adecuadas durante su uso. En términos de estabilidad, el TMG es relativamente estable en condiciones normales, pero puede descomponerse a temperaturas extremas o en presencia de ácidos fuertes. En general, sus propiedades únicas lo convierten en un reactivo valioso en la química orgánica sintética.

CAS:1,1,3,3-Tetramethylguanidine is employed as a polyurethane foam catalyst, as an accelerator for the syntheses of polysulfured rubber. It is also used as a strong base in the photochemical (couplers) and in the pharmaceutical (steroids) industries. It is essential for the preparation of alkyl nitriles from alkyl halides and 3'-alkylthymidines from 3'-nitrothymidines. It serves as an efficient and selective catalyst for the benzoylation of alcohols. It replaces the expensive bases 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) and 1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) in organic synthesis.
