Simple and Green Synthesis of a Novel Fluoro-Nitrato Energetic Plasticizer.

Herein, we report a facile, simple, cost-effective, and green synthesis of a new fluoro-nitrato energetic plasticizer, 2-nitrato-1,3-di(trifluoroethoxy)propane (ACR-ENP-1). Compatible mixtures of ACR-ENP-1 with known binders demonstrated far impressive energetic and mechanical properties of the composite compared to similar composites of same binders with known energetic platicizers.

Addition of CFCl3 to Aromatic Aldehydes via in Situ Grignard Reaction.

Synthetic modification of trichlorofluoromethane (CFCl3) to non-volatile and useful fluorinated precursors is a cost-effective and an environmentally benign strategy for the safe consumption/destruction of the ozone depleting potential of the reagent. In this report, we present a novel method for in situ Grignard reaction using magnesium powder and CFCl3 for synthesis of dichlorofluoromethyl aromatic alcohols.

Stoichiometric self-assembly of isomeric, shape-persistent, supramacromolecular bowtie and butterfly structures.

Two novel macromolecular constitutional isomers have been self-assembled from previously unreported terpyridine ligands in a three-component system. The terpyridine ligands were synthesized in high yields via a key Suzuki coupling. Restrictions of the possible outcomes for self-assembly ultimately provided optimum conditions for isolation of either a molecular bowtie or its isomeric butterfly motif. These isomers have been characterized by ESI-MS, TWIM-MS, (1)H NMR, and (13)C NMR. Notably, these structural isomers have remarkably different drift times in ion mobility separation, corresponding to different sizes and shapes at high charge states.

Peroxovanadium-catalyzed oxidative esterification of aldehydes.

The peroxovanadium species generated from V(2)O(5) and hydrogen peroxide, which is liberated from peroxy salts such as sodium perborate (SPB) or sodium percarbonate (SPC), transform aldehydes directly into esters in an alcoholic medium. Monoesters of diols have been achieved directly in one pot from aldehydes. High catalytic turnover number combined with inexpensive, easily available reagents and innocuous side products from the reaction make it a suitable alternative for the synthesis of esters from aldehydes.
