The relationship between solubilizing ability and characteristics of a micelle has been studied.Triton X-100 micelles solubilized hydrofobic solute such as tetratolylporphine (TTP) and N-methyl-N-hexylaniline (MHA) much more efficiently than sodium dodecy

A versatile metal- and base-free direct reductive amination of aldehydes with amines using formic acid as a reductant under the catalysis of inexpensive BF3·Et2O has been developed. A wide range of primary and secondary amines and diversely substituted aldehydes are compatible with this transformation, allowing facile access to various secondary and tertiary amines in high yields with wide functional group tolerance. Moreover, the method is convenient for the late-stage functionalization of bioactive compounds and preparation of commercialized drug molecules and biologically relevant N-heterocycles. The procedure has the advantages of simple operation and workup and easy scale-up, and does not require dry conditions, an inert atmosphere or a water scavenger. Mechanistic studies reveal the involvement of imine activation by BF3and hydride transfer from formic acid.

Reported herein is the synthesis and application of three novel β-cyclodextrin dimer hosts for the complexation of near infrared (NIR) squaraine dyes in aqueous solution. A series of eight different N-substituted N-methyl anilino squaraine dyes with variable terminal groups are investigated, with an optimal n-hexyl-substituted squaraine guest demonstrating binding constants orders of magnitude higher than the other squaraine–host combinations and comparable to literature-reported systems. Moreover, hydrophobic complexation of the squaraine dyes with the β-cyclodextrin dimer hosts causes drastic changes in the squaraine's photophysical properties, propensity for aggregation and susceptibility to hydrolytic decay.
