Comparison of catalytic activity of hexamethyltriamino- and tri-n-butylphosphines in the Pudovik reaction

The catalytic activity of hexamethyltriaminophosphine in the P(O)?H bond addition to electron-deficient alkenes was studied. Depending on the nature of the alkene, hexamethyltriaminophosphine produces better or lower yields of the reaction products compared to tri-n-butylphosphine.

Pre-organized oligofunctional ligands based on rctt-C-naphthyl-resorcinarene: Synthesis and complex formation

Synthesis of pre-organized oligofunctional ligands based on ortho-methyl-tetra-C-naphthyl-resorcinarene existing in the chair conformation was carried out. By selective modification derivatives differing in the nature of functional groups immobilized on the horizontal and vertical benzene rings of resorcinarene skeleton were obtained. The abilities of the synthesized compounds to form complexes with d-, f-elements and organic amines were considered.

Synthesis of N-Acyl-, N-Sulfonyl-, and N-Phosphinylphospha-lambda5-azenes by a Redox-Condensation Reaction Using Amides, Triphenylphosphine, and Diethyl Azodicarboxylate

The reaction of phosphines and amides with diethyl azodicarboxylate (DAD) produced phospha-lambda5-azenes.Thus aromatic amides and those aliphathic amides with electron-withdrawing substituents gave N-acyl-P,P,P-triphenylphospha-lambda5-azenes (5) when triphenylphosphine (TPP) was employed.Both aryl- and alkylsulfonamides reacted with TPP and DAD to produce the N-sulfonylphospha-lambda5-azenes (9).Diphenylphosphinamide (10) and ethyl carbamate (12) also produced the respective phosphazenes (11 and 13) with TPP and DAD.Secondary carboxamides and sulfonamides did not react with TPP and DAD.The reaction of triethyl phosphite with sulfonamides in the presence of DAD produced the phosphorimidates (20) in an analogous reaction, along with the corresponding N,N-diethylsulfonamides and the deethylated adduct of triethyl phosphite and DAD (23).Triethyl phosphite-DAD failed, however, to give a phosphorimidate with carboxamides but gave, instead, the rearranged adduct of DAD and triethyl phosphite (19).Tris(dimethylamino)phosphine reacted with sulfonamides and DAD but the products were the corresponding ethyl N-sulfonylcarbamates (26) rather than the phosphazenes.Tris(dimethylamino)phosphine reacted with azodicarbonamide (a molecule which contains both the azo and carboxamide groups) with the production of N,N-dimethylurea, again without formation of the phosphazene.Finally, the reaction of triphenylarsine with benzenesulfonamide and DAD produced N-(phenylsulfonyl)triphenylarsa-lambda5-azene (30) but triphenylstibene with DAD and benzenesulfonamide only gave triphenylstibene oxide.Mechanistic possibilities for these reactions are also discussed.

Ylide-Carbene Chemistry. Synthesis of 1,1-Difluoro-1-alkenes

The reaction between nonstabilized alkylidenetriphenylphosphoranes and chlorodifluoromethane has been found to be a useful alternative to the Wittig reaction for the synthesis of many difluoromethylene olefins.Both primary and secondary ylides which do not contain strongly electron-withdrawing substituents within the alkylidene portion of the ylide react with chlorodifluoromethane to give the corresponding difluoromethylene olefins in yields which are significantly better than those obtained by the Wittig reaction.The formation of triphenylphosphine oxide is avoided, and all phosphorus-containing moieties can be recovered and recycled.The reaction proceeds by initial dehydrochlorination of chlorodifluoromethane by the ylide to generate difluorocarbene.The intermediate difluorocarbene is then trapped by a second equivalent of the nucleophilic ylide.Mechanistic evidence indicates that either a zwitterionic intermediate or a three-membered cyclic phosphorane can account for the 1,1-difluoro-1-alkene products.The isolation of several 1-hydro-1-fluoro-1-alkene products such as FCH=CHPh, FHC=CPh2, and FHC=CHCH=CHPh after steam distillation of the reaction mixtures, however, can only be accounted for via a three-membered cyclic phosphorane.

Molecular structures and reactivity of trifluoromethyltris(dialkylamino)phosphonium bromides

Hexa-alkylphosphorus triamides and trifluoromethyl bromide react to give trifluoromethyltris(dialkylamino)phosphonium bromides which were used for the trifluoromethylation of benzaldehyde and copper(I) iodide in the presence of fluoride anions with different counterions; tris(diethylamino)difluorophosphorane proved to be a masked fluoride anion donor.The structures of (1+)Br(1-) and (1+)Br(1-) have been determined by single-crystal X-ray investigations and shown to exhibit a distorted tetrahedral bond configuration with a rather long (F3)C-P bond of 1.866(9) or 1.896(6) Angstroem, respectively. – Keywords: Molecular structures; Reactivity; Trifluoromethyltris(dialkylamino)phosphonium bromides; Single-crystal X-ray determination; NMR spectroscopy

Trialkyl phosphites 1b-c react with compound 5 to give the respective dialkyl phosphate products (9a,b). Moreover, trisdialkylaminophosphines (6a,b) react with 2a and 2b to give the dipolar adducts 10a,b and the phosphonate products 11a,b, respectively.
