- The reaction of arylaldehydes with hexamethylphosphorous triamide and the use of the resulting products for the synthesis of enamines and deoxybenzoins
-
The reaction between the arylaldehydes 1a,b and hexamethylphosphorous triamide 2 leads to the [aryl(dimethylamino)methyl]phosphonic bis(dimethylamides) 3a,b. These can be easily deprotonated by butyllithium in 1,2-dimethoxyethane and condensed with arylaldehydes to afford enamines 4a-f or deoxybenzoins 5a-f in fair to good yield.

-
Irradiation of trans-stilbene oxide with naphthalene-1,4-dicarbonitrile as sensitiser in the presence of electron deficient dipolarophiles leads, via a presumed carbonyl ylide, to various dihydro- and tetrahydro-furans.This chemistry is extended, for the

- The Photochemistry of 2,3-Bis(p-methoxyphenyl)oxirane: Trapping of a C-C Cleaved Intermediate in an Electron-transfer Sensitised Process
-
2,3-Bis(p-methoxyphenyl)oxirane (6) rearranges, with C-O cleavage, to the carbonyl compounds (8) and (9) on irradiation, direct or triplet sensitised, and thermally; in contrast C-C cleavage is observed with dicyanoanthracene as electron-transfer sensitiser, and the resulting intermediate can be trapped by dipolarophiles in synthetically useful reactions.
