| Product | (2,5-Dichloro-3-thenyl)triphenyl phosphonium bromide | HCID 20285664 | — |
Reaction Steps
2,5-Dichloro-3-bromomethyl thiophene (22 g., 90 mmoles) was mixed with 26 g. (99 mmoles) of triphenyl phosphine and 150 ml. of benzene. The mixture was heated to the reflux for 21/2 hours, cooled and filtered to give (2,5-dichloro-3-thenyl)triphenyl phosphonium bromide, m.p. 208-215° C.
