Ultrasound promoted Barbier reactions and Csp3 - Csp2 Stille coupling for the synthesis of diarylmethanes and substituted benzophenones
(Elsevier, 2013-01)
Here we present the preparation of a variety of diarylmethanes obtained via ultrasound Stille coupling under palladium catalysis between some substituted aryl compounds and benzyltributyltin compounds generated through ...
Aqueous Barbier allylation of aldehydes mediated by tin
(Brasil, 2007)
The aqueous tin-mediated Barbier reaction affords good to excellent yields and moderate syn diastereoselectivity under basic and acidic conditions. The high yields and stereoselectivity observed in the case of o-substituted ...
Sonochemical synthesis of bis(tri-n-butylstannyl) aromatic compounds via Barbier-like reactions
(Elsevier, 2013-05-24)
This paper reports a study of the synthesis of aryltri-n-butylstannanes via a sonochemical Barbier reaction of aryl- and heteroaryl bromides with bis(tri-n-butyltin) oxide (2) in THF. Our results demonstrate that, despite ...

Synthetic organometallic radical chemistry in water
(Bentham Science Publishers, 2009-04)
Several organic radical transformations in aqueous media using organometallic chemistry are presented. Group XIV-elements, such as Si and Ge, and Sn-centered radicals make use of novel methodologies in water which employ ...
Estudio de la reacción de Heck a partir del uso de alcoholes alílicos y homoalílicos como sustratos insaturados
(Universidad de los AndesQuímicaFacultad de CienciasDepartamento de Química, 2019)
Las benzo[c]oxepinonas son bloques sintéticos con potencial bioactivo usados en la síntesis de agentes terapéuticos, al igual que ciertas moléculas análogas como las RAL's y las isocumarinas. Estas son de alta importancia ...
