Abstract
1-Alkynyl-1,2-dihydrophosphetes, as prepared by reaction of the approp riate titanacyclobutenes with alkynyldichlorophosphines, rearrange to the corresponding phosphinines via an original 4 pi-cycloreversion-6 p i-electrocyclization mechanism. The reaction of dimethyltitanocene wit h 1,4-diphenylbutadiyne affords a new 3-vinyltitanacyclobut-3-ene that can serve to prepare a 3-vinylphosphinine 6 by the same route.
