Phosphole-N-phenylmaleimide [4+2] cycloadducts as synthetic equivalents of nucleophilic phosphinidenes

Using 1-R-3,4-dimethylphosphole-N-phenylmaleimide cycloadducts as synthetic equivalents of phosphinidenes [R-P], the following sequence has been developed: [R-P] + R1X → RR1PX → RR1P-OR 2. The Royal Society of C

Novel 2-Phosphabicyclo[2.2.2]oct-5-ene Derivatives and Their Use in Phosphinylations

The [4 + 2] cycloaddition of the double-bond isomers (A and B) of dihydrophosphinine oxide 1 afforded novel phosphabicyclo[2.2.2]oct-5-ene derivates (2-4), formation of which was justified by PM3 semiempirical calculations. The compounds of dimer type (2-

A new, stereoselective interconversion of phosphinothio-phosphinoseleno compounds, reduction of phosphinoseleno derivatives and retro pishchimuka rearrangement based on methylthio- and methylselenophosphonium salts chemistry

The interconversion of thiono- into seleno compounds was found to proceed with retention of the configuration at phosphorus and the mechanistic course of this process has been proposed. The isomerization reaction of phosphinothiolates into thiono-isomers via the phosphonium salts has been developed and considered as the "retro Pishchimuka" rearrangement.

Generation and Trapping of a C-Unsubstituted Methylenephosphine Sulphide

The synthesis of a 7-phosphabicycloocta-2,5-diene P-sulphide is described; on thermolysis in boiling toluene, this compound generates Ph-P(S)=CH2 which can be trapped by methanol, 2,3-dimethylbutadiene, and benzylideneacetophenone.

PHOSPHORORGANISCHE VERBINDUNGEN 103. Die ozonolytische Desulfurierung von Thiophosphorylverbindungen: P=S -> P=O

The sulfur atom in thiophosphorylgroups P=S is exchanged by oxygen with retention of configuration according to (1) and (2) as a result of an interaction of the P=S groups with ozone (Table 1 and 2).In dithiophosphinicacidesters only the thionosulfur is easily replaced by oxygen using ozone.The absolute configuration of the enantiomeric methyl-phenyl-phosphinicacid-p-nitrophenylesters 7 an 8 is controlled on the basis of the reaction circle (4).Serine enzymes are blocked by the phosphinicacidesters 7 and 8 by a rate factor of about 60 faster than by the corresponding thionophosphinicacidesters 5 and 6.The phosphinicacidesters 7 (and 8) have a high O-selectivity in competing reactions (7:n-BuOH:n-BuNH2 = 1:1:1) in contrast to the thionophosphinicacidesters 5 (and 6) with no selectivity (ester:amide = 4:6).
