Diethylboron methoxide synthesis
- Product Name:Diethylboron methoxide
- CAS Number:4253-80-9
- Molecular formula:C11H8N2O2
- Molecular Weight:200.19
Yield:4253-80-9 98 %Chromat.
Reaction Conditions:
copper(l) iodide;Phenanthroline;bis(acetylacetonato)palladium(II) in 1-methyl-pyrrolidin-2-one at 160; for 24 h;Product distribution / selectivity;Molecular sieve;
Steps:
69
Examples with a Catalytic Amount of Copper and a Catalytic Amount of Palladium; Examples 56-71 from Table 4, which were performed according to scheme 5 with 1 mmol of aryl bromide and 1.2 mmol of carboxylic acid, demonstrate that the two transition metals are required only in catalytic amounts irrespective of the substrates. To determine the yields, after aqueous workup, the products were chromatographed on silica gel and characterized unambiguously with the aid of NMR, MS, HRMS.
