Foible, According to Webster The part of a sword blade between
the middle and the point. A minor flaw or shortcoming in
personal character or behavior. An eccentric or whimsical liking or
interest in something.

Introduction
Collaborative research, to me, is where two or more individuals work together on a project. Each individual has defined responsibilities, and shares the credit, glory, honor, and (heaven-forbid) blame for the results. Ideally, the collaborators should work as equals, and have input on the planning, direction, and dissemination of the results. In this presentation, I will share some of the collaborative projects I have been involved with, including how the collaboration was initiated, the nature of the collaboration, and the good and bad points of the collaborations.

2-Aminoindanes with Steve Overmann 1984-89 Students got us together (Archie
Thurston and Rick Tolan). 6 students involved: Two went on and
obtained Ph.D.’s (Archie Thurston and Chip Wittenbrink).
I supervised preparations, Steve supervised biological evaluation.
Mike Rodgers did computer interfacing.

2-Aminoindane Conclusions No “really good” compounds were
discovered. We couldn’t obtain external funding. No publications Steve became more interested in other
research projects. 6 presentations at MAS, other
meetings. 2 GRFC grants.

NASA-JOVE: Preparation of Non-Linear Optical (NLO) Materials 1993-8 NASA invited Southeast to participate. I had to find a NASA colleague to work
with. Spent one summer at Marshall Space Flight
Center and the Univ. Alabama - Huntsville in Huntsville, AL.
6 students involved (Jennifer Mabery, Jamie Carrigan, Angela Scates, Pat Zimmermann, Brian Taylor, Jeremy Wittenborn).

NASA-JOVE “Good News” Money for summer salary, student
workers, travel, operations. Summer JOVE meetings in Texas,
Florida, and California. Three publications and several
presentations by my students and I from the work we did.
Led to further collaboration.
![Page 15: Fun, Foibles, and Follies In Collaborative Research](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56814033550346895dab96fa/html5/thumbnails/15.jpg)
NASA-JOVE “Bad News” My collaborator was only interested
in his compound, “DAMNA”, and did little with 25 we made.
He only contacted me when he wanted me to make more of his compound.
He never made me a co-author on any of his publications, nor acknowledged the work I did.

Rainer Glaser: NLO Materials 1997 - present We met at Organic Chemistry Day
at University of Missouri, when I presented a poster on NASA-JOVE research.
I prepare NLO materials, and Glaser gets X-ray structures and does theoretical calculations.

Glaser Results Two publications and one
presentation. I received an ACS-PRF grant for my
part of the research. Four students have been involved
(Gary Bohnert, Scott Kirkley, Rachel Phillips, Steve Updike), one who is in the Ph.D. program at Missouri (Gary Bohnert).

Preparations of Ketenes with Jin Gong. Begun seriously in 1999 (some
informal consulting earlier). I supervise preparation of ketenes,
and Jin’s students react them with transition metal complexes.
Jin pays for one student (Andy Gilbert) whom I supervise.

Ketene Results Seven different ketenes have been
prepared. Some ketene complexes have
been prepared. At least one presentation will be
made this year.
