Guidance literature:

With catalyst: 15-crown-5; In neat (no solvent); addn. of allyl bromide to stirred mixt. of Sn and 15-crown-5 (90-100°C, N2 stream); evapn. in N2 stream (80-100 Torr, 40°C), fractionation; elem. anal.;

Reference yield: 84.3%

tin (7440-31-5) + allyl bromide (106-95-6) + mercury dichloride → Diallyltin(IV) dibromide (17381-88-3)

Guidance literature:

With triethylamine; In toluene; (Ar); addn. of HgCl2 to a suspn. of Sn-powder in toluene; then reflux the mixt. for 30 min; after cooling of the mixt. addn. of triethylamine and reflux it again; now dropwise addn. of allyl bromide with efficient stirring for 2 h;; cooling the mixt. to room temp.; filtration; evapn. of the filtrate; vacuum distn. of the resulting oil;;
