Borohydride reductive amination a la LabTop | Bookmark | ||||||
I feel like trying the protocol that LabTop wrote a long time ago on Rhodium's website. I will use the same ratios given by him. I just have a question about it: He states to gas in chilled acetone. I was under the impression that gassing in acetone wasnt so good, as it can lead to a lot of side products. Am I right? I will be doing a 1/10 of his write-up. How long should i let it stir in the end? I'm guessing, less then what's advised on his write-up since I'm doing 1/10 scale. Any thoughts on this? |

Use the latest method from Barium. | Bookmark | ||||||
See my last remark in the sticky thread, Barium has posted a much better procedure, without need to use gaseous methylamine, but uses the salt in WATER! Thought that the message should have hit home by now, look at the date I posted that. LT/ WISDOMwillWIN |

Oooops! | Bookmark | ||||||
That one is only in the Methods forum : Post 443313 (LaBTop: "Hydrous Boro One Pot ! AT LAST!", Methods Discourse) Have placed a message in this forum also now (really thought I had done that at the same time then, that's probably why there was such a shallow followup from Newbees!) Look for it now also in Newbee forum, "First read for Members new and old", last post now. LT/ WISDOMwillWIN |
