The reaction of 4-(1,3,2-benzodioxaphosphol-2-yloxy)-3-tert-butylpent-4-en-2-one with hexafluoroacetone

Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.

The reaction of a 1:1 monomer feed ratio, explained by a mechanism of propagation via zwitterion intermediates, proceeds without any added catalyst to give an alternating copolymer 3 involving ring-opening of 1 and ring-closing of 2. The structure of copolymer 3 was determined by H-1, C-13 NMR, P-31 NMR and IR spectroscopies as well as elemental analysis.
