The reviewers feel that it could be of interest for future developments of transition metal complex photochemistry and its possible application in biologically important systems to make use of labeled metals. Therefore,... 

An impressive example of the possibilities of metal complex photochemistry is the substantiation of the critical step in corrin synthesis reported by Eschenmoser 145> Ring closure is brought about by antara-facial cycloisomerization of a secocorrinoidic palladium complex by photochemical 1.16-hydrogen shift.

To date, most of the photochemical data available for transition metal complexes comes from condensed phase studies (1). Recently, the primary photochemistry of a few model transition metal carbonyl complexes has been investigated in gas phase (5.). Studies to date indicate that there are many differences between the reactivity of organometallic species in gas phase (5.6) as conq>ared with matrix (7-10) or solution (11-17) environments. In most cases studied, photoexcitation of isolated transition metal... 

Since the early 1970s, coordination chemistry and photochemistry have combined to allow development of a wide range of responsive metal complexes. These allow non-invasive monitoring of metal ion concentrations. Time-resolved measurements are particularly powerful, since they allow detection of very small amounts of substrate and have optimal signal-to-noise ratios. Nonetheless, much remains to be done using the tools which these early studies have provided, particularly with reference to the development of effective sensor systems for a range of ions by time-resolved techniques. 

It has been our goal for some time to run photochemical energy storage reactions without relay molecules or separate catalysts. We have concentrated on the photochemistry of polynuclear metal complexes in homogeneous solutions, because we believe it should be possible to facilitate multielectron transfer processes at the available coordination sites of such cluster species. 

Job and Curtis investigated the photochemistry of cr-bonded (CH3 )2GeCH=CH2 derivatives of metal carbonyls98, in an attempt to produce species with jr-allyl coordination. Three different metal complexes were examined, giving different types of product in each case, as shown in reactions 49-51. No jr-allyl products were formed, however.
