Hydroformylation of terminal alkenes in alcohol solvents leads to the selective formation of the corresponding acetals. The Xantphos ligand gave the best results as well as acetal selectivities higher than 99% and linear/branched ratios of up to 52 were obtained. The scope of the reaction was studied. Acetals were found to be unreactive under hydroaminomethylation conditions.
在醇溶剂中末端烯烃的加氢甲酰化导致相应缩醛的选择性形成。Xantphos配体提供了最佳结果,乙缩醛选择性高于99%,线性/支化比高达52。研究了反应范围。发现缩醛在氢氨甲基化条件下不反应。
