Dibutyltin chloride

Dibutyltin. A larger data set exists for dibutyltin, including both acute and long-term test results. The lowest concentration identified was a chronic NOEC of 0.015 mg/1 for Daphnia magna exposure to dibutyltin chloride. Long-term values were available across three trophic levels, and, therefore, an uncertainty factor of 10 was considered appropriate.

Allylation. Carbonyl compounds are converted into homoallylic alcohols with allyl bromides-tin, diallyldibutylstannane, or allyltributylstannane-dibutyltin chloride. All three protocols require the presence of Me,SiCl (although acid chlorides may replace MCjSiCl in the last reaction).

The solid-phase total synthesis of (S)-zearalenone by Nicolaou et al. (372) started with the preparation of the resins 488 and 489 from the Merrifield resin (486, Scheme 9.1). Oxidation, followed by olefination of the resulting aldehyde, gave a polystyrene vinyl resin (487), which was converted into dibutyltin chloride 488. In this process, the stannylation reagent n-Bu2SnHCl was formed in situ from -Bu2SnCl2 and n-Bu2SnH2. Reduction of 488 yielded the polymer supported tin hydride 489. 

One major drawback of the Stille coupling in general is the presence of tin impurities in the final product. To solve this problem, polymer-bound tin reagents can be used. Her nan et al. [88] synthesized both dimethyl- and dibutyltin chloride resins, and used them in a model reaction shown in Scheme 26. Substoichiometric rather than catalytic amounts of resin 41 were needed in order to obtain acceptable yields, and the usual Stille conditions had to be optimized to fit this specific reaction. The catalytic system consisted...
