Three aldehydes (4a-c) are transformed into 1,1-dibromides (6a-c) by 2,2,2-tribromo-2,2-dihydro-1,3,2-benzodioxaphosphole (2).This reagent (2) is also very active in the cleavage of ethers; its reactions may show some features of carbonium as well as of SN2 character.

The reaction of 1,1-bistrifluoromethylsulfonyloxy-alkanes (2) with magnesium iodide in carbon disulphide at O deg C affords 1,1-diiodoalkanes (3-I) in good yields.No rearrangement products are observed.The reaction of 2 with magnesium bromide in carbon disulphide or titanium tetrachloride in dichloromethane yields either 1,1-dichloro- (3-Cl) or 1,1-dibromoalkanes (3-Br).Rearrangements products are formed from α-branched substrates.
