|Research in the Macdonald group consists of
the experimental and theoretical investigation of main
group compounds in unusual bonding environments and
oxidation states. We use such investigations to
explore and explain the chemistry of the "rest" of the
periodic table that does not conform to the rules of
organic chemistry (i.e. most of the elements in the
periodic table). The knowledge gained from the
fundamental investigations is used to design new
reagents and materials.
Our current investigations include:
The synthesis and development of compounds containing main group elements in unusually low oxidation states. The compounds we are making are useful for the synthesis of many other types of main group and transition metal compounds and as precursors for new materials.
Examples of such compounds from group 15 include the stabilized P(I) salt [(dppe)P][I] shown on the left and the As(I) salt [(dppe)As]2[SnCl6]. The iodide salts have proven to be useful reagents for the syntheses of various other interesting molecules and materials including phosphamethinecyanine dyes, clusters and oligomers, as illustrated below.
The synthesis and chemistry of main group metallocenes and their analogues. These compounds are of interest for their unusual structural features, their peculiar reactivity and their utility as precursors for the formation of new or valuable materials.
We have shown that the half-sandwhich compound Cp*In can be used to generate new stable, low-oxidation state compounds such as [In][OTf]. This In(I) salt has proven to be superior in terms of solubility and stability with respect to In(I) halides and it has been exploited as a reagent by our group and several other research groups around the world.
I have collaborated with many other researchers in Canada and around the world; graduate students in my group can expect to participate in at least one collaboration while they are here.
Some of my past and present collaborators include:
