, p. 5763 - 5768 (2005)
Novel cyclic host molecules were synthesized by the insertion of three types of aromatic spacers into the skeleton of permethylated α-cyclodextrin. These host molecules formed a 1:1 complex with sodium 3- and 4-nitrobenzenesulfonates (3- and 4-NBS), and s
Molecular weight distribution and endgroup functionality of poly(2-ethyl-2-oxazoline) prepolymers
Celebi,Barnes,Narang,Kellogg,Mecham,Riffle
, p. 147 - 156 (2015)
Control over molecular weight distribution and endgroup functionality is important for prepolymers that are to be further incorporated into block and graft copolymers. Monofunctional, telechelic and heterobifunctional poly(2-ethyl-2-oxazoline) (PEtOx) oli

Six dendrimer and dendron cores terminated by hydroxyl groups that are neither phenolic nor cleavable by hydrogenolysis have been prepared in a consistent one-pot manner from terminal allyl groups by reduction of the product of reductive ozonolysis. Some of the terminal allyl derivatives are new and others have been prepared by new methods. The well-known O-benzylidene derivative of 2,2′-bis(hydroxymethyl)propanoic acid was shown to be the cis-stereoisomer. A new AB3-type anhydride, tris(benzyloxymethyl) acetic anhydride has been prepared. It was demonstrated that these cores and dendrons could be assembled into first and second generation homo- and mixed polyester dendrimers.
Silicaphosphine (Silphos): A filterable reagent for the conversion of alcohols and thiols to alkyl bromides and iodides
Iranpoor, Nasser,Firouzabadi, Habib,Jamalian, Arezu,Kazemi, Foad
, p. 5699 - 5704 (2007/10/03)
Silicaphosphine (Silphos), [P(Cl)3-n(SiO2) n], as a new heterogeneous reagent is introduced. This reagent converts alcohols and thiols to their corresponding bromides and iodides in the presence of X2 (X=Br, I) in refluxing CH3CN in high to quantitative yields. Use of Silphos provides a highly practical method for the easy separation of the Silphos oxide byproduct by a simple filtration.
An alternative method for the highly selective iodination of alcohols using a CsI/BF3·Et2O system

, p. 2531 - 2540 (2007/10/03)
A variety of allylic and benzylic alcohols have been converted into the corresponding iodides using cesium iodide (CsI) in the presence of boron trifluoride etherate (BF3·Et2O) in acetonitrile under mild conditions.
Silica Chloride (SiO2-Cl), a New Heterogeneous Reagent, for the Selective and Efficient Conversion of Benzylic Alcohols to Their Corresponding Chlorides and Iodides
Firouzabadi, Habib,Iranpoor, Naser,Karimi, Babak,Hazarkhani, Hassan
, p. 3671 - 3677 (2007/10/03)
Structurally different benzylic alcohols were efficiently converted to their corresponding chlorides by silica chloride (SiO2-Cl) in CHCl3 at room temperature. Silica chloride is also able to convert benzylic alcohols to their iodides in the presence of NaI in a mixture of CH3CN/CHCl3 in excellent yields.
