I know its in excess, but why isn't the same ratio applied to both ketones. And (btw) I tried the TFSE first. Here at the Hive its all about improving methods, and understanding the principles behind those methods. So dont get so uptight.Thanks for the input but you really did'nt help increase knowledge base. The insight I was inquiring about was, in decreasing the amount of methylamine in NaBH4 Reductive Alkylation of P2P.If you havent't performed the reduction, you really have no experience, theory is all well and fine, but I live in the real world, and all reagents are precious.
