Abstract A procedure for preparing 3-, 4-halomethyl derivatives of 5-tert-butylfuran containing elec-tron-withdrawing substituents in position 2 was developed, and phosphorylation of the resulting productsunder the conditions of the Arbuzov and Michaelis- Becker reactions was studied. 3-Bromomethyl derivatives are phosphorylated with trimethyl phosphite considerably faster than their 4-chloromethyl analogs. At the same time, 3-and ...
