Multistep Reaction Sequence: Benzaldehyde to Benzilic Acid ..

AB - In this report, we present methods of functionalization of AuNP's with deep-cavity cavitands that can include organic molecules. Two types of deep-cavity cavitand-functionalized AuNP's have been synthesized and characterized, one soluble in organic solvents and the other in water. Functionalized AuNP soluble in organic solvents forms a 1:1 host-guest complex where the guest is exposed to the exterior solvents. The one soluble in water forms a 2:1 host-guest complex where the guest is protected from solvent water. Phosphorescence from thiones and benzil included within heterocapsules attached to AuNP was quenched by gold atoms present closer to the guests included within deep-cavity cavitands. During this investigation, we have synthesized four new deep-cavity cavitands. Of these, two thiol-functionalized hosts allowed us to make stable AuNP's. However, AuNP's protected with two amine-functionalized cavitands tended to aggregate within a day.

Multistep Synthesis of Benzilic Acid - Essay Samples

Benzil, also known as dibenzoyl or bibenzoyl, is an organic compound used as a photoinitiator in polymer chemistry. Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use. These materials may or may not have a Certificate of Analysis available.

The diorganotin dibenzilates on the other handhave a cis- R2SnCl 2 or distorted octahedralstructure.

Heartfelt thanks to the following who helped advance this projectto where it is today: to Dr. James C. Kelley, former Dean of theCollege of Science and Engineering, Dr. James Orenberg, former Chair,and Dr. Clifford Berkman, Chair, Department of Chemistry andBiochemistry, for supporting our interest in exploring new ways toutilize the internet as additional means to teach students laboratorytechniques in Chemistry; Dr. Meden Isaac, Dr. Margareta Sequin, andMs. Kathy Munderloh for sharing their experiences in teaching Chem334; to my Chem 334 students for beta testing and Talitha Marty,Clint Ives, Randall Medefesser, Kristin Persson, and Cordellia Leefor their help in the experimental set-ups shown on-line; to my Chem452 student, Diana Shem for helping with the instrument measurementset-ups with error analyses; Fall 2004 Chem 334 students acrossseveral sections volunteered to evaluate compatibility of the newMicro-Kits for our GC experiments: M. Azimi, Sabrina Kim, KarthikEkambaram (Expt. #3), and Raymond Castillo, Randy Tanega, Tong-NaNgoy, Tony Hsiao (Expt. #8), modification in Expt. #8 greatlyimproved the lab experiment; SFSU's Division of InformationTechnology (DoIT) and Center for the Enhancement of Teaching (CET).Initial gradient HPLC separation of benzoin and benzil by Dr. GaryTakeoka (USDA, Albany, CA) is greatly appreciated, which helped us torapidly set-up a method for isocratic HPLC separation.
