Procedure

Using a method similar to that of Example 1, 88 parts of 2-methyl-2-ethylhexanoic acid chloride and 108 parts of methoxydiphenylphosphine give 165 parts of 2-methyl-2-ethylhexanoyl-diphenylphosphine oxide as an oily crude product. Column chromatography over silica gel (eluant: a 3:1 mixture of toluene and ether) gives the product as a pale yellowish oil. Yield 154 parts (90% of theory).
