Vogel Phenylacetic preparation ? | Bookmark | |||||
This looks wrong : ![]() I thought that dry ice was also needed. Also, can carbon dioxide gas be bubbled into the grignard rxn instead of using dry ice ? I've got nothing to do today but smile ! |

Since that's a cognate preparation, one must look at the above synthesis to find little details like using carbon dioxide ![]() ![]() |

I did this reaction once on a highly substituted benzyl chloride by simply throwing chunks of frozen CO2 into the flask containing the grignard and the yields were pretty good. Don't bother with powdering etc, you will introduce too much water. Just crush the CO2 enough so it will go through the joint. I'm not fat just horizontally disproportionate. |
