WebFeb 12, 2007 · 1. Under salt-free, aprotic conditions, ylides Ph 3P=CHR (R=alkyl, alkenyl, phenyl) react with aldehydes to produce the oxaphosphetane directly via four-centered transition states. 2. The Z:E ratio of alkenes corresponds to the cis-trans ratio of oxaphosphetanes in typical reactions (kinetic control). WebMany of the physical properties of alkenes and alkanes are similar: they are colorless, nonpolar, and combustible. The physical state depends on molecular mass: like the corresponding saturated hydrocarbons, the simplest alkenes ( ethylene, propylene, and butene) are gases at room temperature.
