Esta reacción es conocida como síntesis de Williamson. lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918809484 2020-11-12 23:23:50 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918809484 lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918811990 2020-11-12 23:25:22 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918811990 Esta reacción transcurre a través del mecanismo SN2.La importante basicidad de los alcóxidos produce reacciones de eliminación con sustratos secundarios y terciarios, formando alquenos en lugar de éteres. lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918812588 2020-11-12 23:25:43 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918812588 lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918813990 2020-11-12 23:26:40 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918813990 Otra situación en la que Williamson no rinde éteres, es en el caso de emplear alcóxidos impedidos, como tert-butóxido de potasio. Debido a su gran tamaño el tert-butóxido elimina incluso con sustratos primarios. lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918815700 2020-11-12 23:27:42 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918815700 lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918816110 2020-11-12 23:27:58 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918816110 Con haloalcanos primarios y sobre todo con haloalcanos que carecen de hidrógenos b el rendimiento de Williamson es muy bueno. lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918816831 2020-11-12 23:28:28 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918816831 lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918817586 2020-11-12 23:28:57 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918817586 Bibliografia lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918818593 2020-11-12 23:29:38 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918818593 los éteres rompen en presencia de ácidos, debido a la protonación del oxígeno, generando alcohol y haloalcano. En exceso del ácido el alcohol puede transformarse en un segundo equivalente de haloalcano (en caso de ser simétrico el éter). lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918831454 2020-11-12 23:37:44 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918831454 Ruptura de éteres catalizada por ácidos lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918832270 2020-11-12 23:38:15 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918832270 lizbethquintana223 https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918833450 2020-11-12 23:38:59 UTC https://padlet.com/lizbethquintana223/gvstpkl6nj6yc1cy/wish/918833450
