Hept-3-ene

The decomposition following FI of variously 13C- and D-labelled hept-1-enes have been studied over the time range from tens of picoseconds...

The interaction of a alk-l-ene and phosphorus pentachloride to form a complex of the general composition RCH=CH2 2PCl5, now recognized as having the phosphonium salt structure 73, has been known for some time. Very many examples are now known of the decomposition of such complexes with SO2 (or in some cases with P40io ) under controlled conditions when the products are (2-chloroalkyl)phosphonic dichlorides (74) or derivatives thereof. The acids from but-l-ene and pent-l-ene hex-l-ene and hept-1-ene and oct-l-ene and dec-l-ene ° have all been reported. The stability of the initial adducts appears to very considerably, and dehydrochlorination may occur readily if the reaction is carried out with insufficient control. Vinyl and isopropenyl esters of carboxylic...

An hypothesis known as Bredt s Rule states that a double bond to a bridgehead of a smallring bridged bicyclic compound is not possible. The basis of this rule can be seen if you attempt to make a model of bicyclo[2.2.1 ]hept- 1-ene, A. One approach to the assembly of this model is to try to bridge the number 1 and number 4 carbon atoms of cyclohexene with a methylene (CH2) unit. Compare this bridging with the ease of installing a CH2 bridge...
