Natural Science Forum / Chemistry / Organic Synthesis / June 2005POCl3 + alkene = ?
Hello, all! Could anyone help me to find an answer to the following question: what are the products of the interaction between POCl3 and an alkene? What is a mechanism of this reaction? Thanks in advance, Dmitry. > Hello, all! > > Could anyone help me to find an answer to the following question: what > are the products of the interaction between POCl3 and an alkene? What > is a mechanism of this reaction? The quick answer is "no reaction." An alkene with an average alkene reactivity bellow ca.200 ?C will not react with POCl3 ?with no help of catalysis? to any appreciable extent. I suppose that given enough temperature or under the help of some catalysis something will happen, and we could expeculate about the result for long, but, as long as I know, this is not part of the standard synthetic techniques. Some adventitious water could react with POCl3 resulting in HCl that could add to some alkenes producing alkyl chlorides. Best regards. Gabriel Tojo |
