Web3 feb. 2011 · Using the conventional Williamson ether synthesis, n -butyl ether was prepared from sodium hydroxide, n -butyl alcohol, and n -butyl chloride using excess of the alcohol as solvent in 61% yield after 14 h reaction time. However, when the excess alcohol was replaced by dimethyl sulfoxide, the yield of ether rose to 95% with 9.5 h reaction time. WebIn general, four different approaches are used to synthesize dendrimers: 1. Divergent synthesis in which dendrimers grow outwards from the core, diverging into the space 2. Convergent synthesis, in which dendrimers are built from small molecules that end up at the surface of the sphere 3.
