Reaction Steps
Octadecan-1-ol (1a) (520 mg, 1.92 mmol) and Ph3P (550 mg, 2.10 mmol) were dissolved in CH2Cl2 (25 mL). The mixture was cooled in an ice bath and CBr4 (630 mg, 1.90 mmol) was added with stirring. The mixture was allowed to warm to r.t. and was stirred overnight, then it was concentrated under a stream of N2 and the residue was subjected to flash column chromatography on silica, eluting with hexane, to afford 1-bromooctadecane (2a) (605 mg, 96%) as a waxy solid; mp 26-28° C.
