Issue Date: | 1999 | Citation: | Tetrahedron Letters. 40:4 (1999) 789-792 | Abstract: | [alpha]-Oxophosphonium ylides (3a-3e) react with N-chlorosuccinimide and N-bromosuccinimide in the presence of azidotrimethylsilane giving the corresponding haloazidoalkenes (4a-4g) with elimination of triphenylphosphine oxide. These compounds were completely converted to the 2H-azirines 5a-5g on heating in heptane. | URI: | https://hdl.handle.net/10316/5271 | DOI: | 10.1002/chin.199915131 | Rights: | openAccess |
