Phosphaalkenes 1a-h react with 2,3-dimethylbutadiene (2) to yield the 1,2,3,6-tetrahydrophosphinines 3a-h. 3a-g exist in two diastereomeric forms, which can be interconverted thermically under inversion at the phosphorus atom.This is proved by means of X-
PHOSPHAALKENE ALS EN-KOMPONENTEN IN (4+2)-CYCLOADDITIONEN.

The phosphaalkenes 1 and 3 undergo cycloadditions with dimethylbutadiene forming the 1,2,5,6-tetrahydro-λ3-phosphorines 2 and 4.In each case two stereoisomers are obtained, one of which can be converted thermically into the more stable on
