Cyclotetra((lambda3-phosphazanes) derivant de diamines-1,2. Precurseurs de composes du phosphore dicoordonne

Cyclotetraphosphazanes 2 and 5 obtained from 1,2-diamines are 1,3,2-diazaphosphole oligomers leading to the monomeric form by either thermal equilibrium or by complexing with boron trifluoride.The dicoordinated form stabilized by an orthophenylene ring could explain the reactivity of 4,5-benzo 1,3,2-diazaphosphole 3 with compounds having a mobile hydrogen; these reactions were a 1.2 type addition while butanol led to a 1.1 type addition with complexed 1,3,2-diazaphospholes 4 and 8.

Highly selective markovnikov addition of hypervalent H-spirophosphoranes to alkynes mediated by palladium acetate: Generality and mechanism

Palladium acetate efficiently catalyzes the addition of an H-spirophosphorane (pinacolato)2PH to alkynes to give Markovnikov addition products highlyselectively. The addition products can be easily converted to the corresponding alkenylphosphonates and phosphonicacids viasimple hydrolysis or thermal decomposition. This new reaction isa general method for the introduction of phosphorus functionality to the internal carbons of terminal alkynes, resolving the problem of the regioselectivity associated with hydrophosphorylation reactions so far reported. Mechanistic studies confirmed that (a) palladium acetate was reduced to metallic palladium by H-spirophosphorane, (b) the P-H bond of H-spirophosphorane could be activated by zero-valent platinum complexes to give the corresponding hydridoplatinum complexes, and (c) an alkenylpalladium species was identified from the reaction of palladium acetate with H- spirophosphorane and diphenylacetylene. These results support a reaction mechanism that palladium acetate was first reduced by H-spirophosphorane to give zero-valent palladium. This zero-valent palladium might insert into the P-H bond of the H-spirophosphorane to give a hydridopalladium species which then added to alkyne via the addition of H-Pd bond to form an alkenylpalladium species with the hydrogen atom added to the terminal carbon of alkynes. Reductive elimination of the alkenylpalladium affords the addition product.

?Design of Experiments? as a Method to Optimize Dynamic Disulfide Assemblies: Cages and Functionalizable Macrocycles

Cyclophanes are a venerable class of macrocyclic and cage compounds that often contain unusual conformations, high strain, and unusual properties. However, synthesis of complex, functional derivatives remains difficult due to low functional group tolerance, high dilution, extreme reaction conditions, and sometimes low yields using traditional stepwise synthetic methods. ?Design of experiments? (DOE) is a method employed for the optimization of reaction conditions, and we showcase this approach to generate a dramatic increase in the yield of specific targets from two different self-assembling systems. These examples demonstrate that DOE provides an additional tool in tuning self-assembling, dynamic covalent systems.

Benzylic Newman-Kwart rearrangement of O-azidobenzyl thiocarbamates triggered by phosphines: pseudopericyclic [1,3] shifts via uncoupled concerted mechanisms

A series of O-(o- and p-azido)benzyl thiocarbamates smoothly rearranged in the course of Staudinger imination reactions with tertiary phosphines, giving rise to the respective S-(o- and p-phosphinimino)benzyl thiocarbamates as a result of an oxygen to sulfur migration of the functionalized benzyl group. By contrary, their m-azido isomers did not rearrange under similar conditions. Computational investigations using DFT methods revealed the uncoupled concerted mechanisms of these 1,3-benzyl shifts via polar transition states with pseudopericyclic orbital topologies, with the benzyl group migrating in the plane of the thiocarbamate fragment.
