• Photochemistry of matrix-isolated (.alpha.-diazobenzyl)phosphonate. Observation and reactions of phosphonylphenylcarbene, phosphonyl phenyl ketone oxide, and phenylphosphonyldioxirane

  Photolysis of dimethyl alpha-diazobenzylphosphonate (1) in an Ar matrix at 10 K resulted in the appearance of new absorption bands at 1268, 788, and 536 cm-1, attributable to the carbene 2. The assignment was based on the observation that the new absorptions disappeared upon thawing of the CO-containing matrix to produce the ketene 3, which can be generated by photolysis of (alpha-diazophenacyl)phosphonate 4. Photolysis of 1 in an Ar matrix doped with 20% O2 at 10 K produced benzoylphosphonate 5 along with benzoyl phosphate 8. Generation of 2 in a 0.3% O2-containing matrix, followed by warming of the matrix to 35 K in the dark, resulted in the total disappearance of the band arising from 2 and the concurrent appearance of a new intermediate, identified as the carbonyl oxide 6. Photolysis of 6 with visible light (lambda > 480 nm) gave the corresponding dioxirane 7, which was converted to the ester 8 by further irradiation (lambda > 350 nm); none of the phosphate 9, expected to arise via phenyl migration in the photoisomerization of 7, was detected.

  The reaction between trimethylsilyldiazomethane and aryl or vinyl ketenes 2 and 7, bearing an electron withdrawing group on the ketene moiety, gave rise in moderate to good yields to the trimethylsilylated styrenes 3–5 or 1,3 dienes 8a-d resulting from the decarbonylation of presumed intermediate cyclopropanones.
