Synthesis of diisopropoxymethylboraneTriisopropylborate (11O g, 0.585 mol) was added to trimethylboroxin (55 ml of a 50 wt% solution of trimethylboroxin in THF, 0.20 mol) under nitrogen and stirred for 5 minutes. The resulting clear solution was heated to distill off the desired diisopropoxymethylborane through a Vigreux column. The first fraction (22 g, distilling between 66-71 ⁰C) contained mostly THF and a small amount of isopropanol. The second fraction (53 g, distilling between 74-100 ⁰C) contained 81 wt% diisopropoxymethylborane and 19 wt% THF. The third fraction (24 g, distilling between 100-112 ⁰C) contained 87 wt% diisopropoxymethylborane and 13 wt% triisopropoxyboroxin. The overall yield of diisopropoxymethylborane was 75.8 % relative to the borate employed.
