Divergent reactivity of nucleophilic 1-bora-7a-azaindenide anions
The reactions of 1-bora-7a-azaindenide anions, prepared in moderate to excellent yields by reduction of the appropriate 1-bora-7a-azaindenyl chlorides with KC8 in THF, with alkyl halides and carbon dioxide were studied.

Synthesis, spectroscopic characterisation and transmetalation of lithium and potassium diaminophosphanide-boranes
Deprotonation of a secondary diaminophosphane-borane yields lithium and potassium diaminophosphanide-boranes which undergo transmetalation to yield isolable Cu(I) and Zn(II) complexes.

Accessing multimetallic complexes with a phosphorus(I) zwitterion
The synthesis of a zwitterionic triphosphenium molecule which acts as a multidentate donor with various zero-velent transition metal complexes is presented. These mono- and bimetallic complexes can either be bound through the P(I) center or through the cyclopentadienyl moiety on the backbone of the molecule.

About this collection
Professor Philip P. Power, an icon of organometallic chemistry, turns 65 in April 2018. Phil is a distinguished Professor of Inorganic Chemistry at the University of California, Davis. Having completed his BA (Chemistry) at Trinity College, Dublin in 1974, Phil received his PhD under Professor Michael F. Lappert, FRS in 1977. After this time, Phil worked as a postdoctoral researcher with Professor Richard H. Holm at Stanford, before taking up a position at Davis in 1981.
In honour of this anniversary, we have collected 27 of Phil’s contributions to RSC journals, and thank over 45 of his previous co-workers, and chemists whose work is allied to Phil’s for contributing original research to this special collection. These papers reflect Phil’s wide-ranging interests and propensity for timely research, as well as his provision of a range of useful and often field-defining reviews.
Since 1981, Phil has been the recipient of a plethora of awards, fellowships, prizes and honorary lectureships. His scientific excellence is beyond question, and working with Phil is a thoroughly enjoyable, if cerebrally challenging, experience. Phil’s lab has been a stepping stone in many chemist’s early career and he has had a dramatic impact on organometallic and inorganic chemistry. We have all worked with Phil either as postdoctoral fellows, or hosting him as a visiting professor and hope these papers, and our editorial, reflect his unique approach to science as well as his unique character.
These papers will be free-to-access for the next two months so please join us in celebrating the birthday of a titan of organometallic chemistry through some of the highlights of his career to date, and through the fantastic new research proffered by other researchers in the field.
