Br (CH2) 4Br and NaO (CH2) 2CHCH2 react under suitable conditions to give Br (CH2) 4O (CH2) 2CHCH2 (55%), which is treated with KPPh2 to yield the ether-containing phosphine Ph2P (CH2) 4O (CH2) 2CHCH2 (83%). The reaction of CH3CH2OC (O) CHC (CH3) 2 and BrMg (CH2) 3CHCH2 in the presence of CuCl (cat.) and ClSiMe3 yields CH3CH2OC (O) CH2C (CH3) 2 (CH2) 3CHCH2 (67%), which is reduced to an alcohol that is brominated, ...
