UNEXPECTED PRODUCTS IN A KABACHNIK-FIELDS SYNTHESIS OF AMINOPHOSPHONATES

In a Kabachnik-Fields synthesis of aminophosphonates derived from aromatic ketones the formation of hydroxyphosphonates, their rearrangement to corresponding phosphates and amine promoted decomposition of the last, leads to a number of unexpected products, which in some cases could be the only products of reaction.Key words: 1-Aminophosphonates; 1-hydroxyphosphonates; Kabachnik-Fields reaction; phosphonate-phosphate rearrangement.

Laser flash photolysis of 9-diazofluorene in low-temperature glasses

The laser flash photolysis of 9-diazofluorene was investigated in several viscous organic glasses at low temperature. The data indicate that triplet fluorenylidene reacts with "soft warm" glasses by classical H atom abstraction, but the mechanism changes to quantum mechanical tunneling in colder and more rigid matrices.

Reinvestigation of the Chemistry of Arylcarbenes in Polycrystalline Alcohols at 77 K. Secondary Photochemistry of Matrix-Isolated Carbenes

Photolysis of diphenyldiazomethane (DPDM) in frozen alcoholic matrices gives ground-state triplet diphenylcarbene (DPC).At 77 K 3DPC reacts primarily with alcohols by OH insertion to give ethers.Photolysis of 3DPC produces an excited carbene 3DPC* which reacts with the matrix by H-atom abstraction to ultimately give alcohol-type products.Secondary photolysis of triplet fluorenylidene at 77 K is not as prevalent as that of 3DPC.

Irradiation of Diazofluorene in Alcohols: Unusual Behaviour of Fluorenyl Ethers

Fluorenyl ethers formed in the reaction of singlet fluorenylidene with alcohols undergo photocleavage to give fluorene and fluorenone, which formally arise from triplet fluorenylidene.
