Hbf4 ether
WebOct 29, 2015 · Graphical Abstract The activity of HBF 4 (aq. solution) as a catalyst in propargylation reactions is presented. C–O, C–N and C–C bonds were formed in technical acetone and in air. Good to excellent yields were obtained using low acid loading (typically 1 mol-%) under mild reaction conditions. Abstract http://wrg.rice.edu/Whitmire_Research_Group/q059.html
