The ?eld of metal boron chemistry has been an especially active one since the 1960s. Much of the early work centered on the synthesis and structural characterization of polyhedral metallaborane and metallacarborane clusters, which will not be discussed in the current Volume. However, early work on metal boryl complexes by Nöth et al. also appeared during this period, - thoughthe?rstsimple metalborylcomplexestobestructurallycharacterized bysingle-crystalX-raydiffractionwerenotreporteduntil1990(indeed,crystal structuresofiridiumhydridoborylcomplexeswerereportednearlysimulta- ouslybyBaker,Marder,etal. [1]andbyMerolaetal. [2]),andthisnewinterest in the area arose speci?cally as a result of the report by Nöth et al. [3] on the rhodium-catalyzed hydroborationof alkenes using catecholborane. Although there had been previous reports of metal-catalyzed hydroboration employing polyhedralboranesorcarboranesastheB Hsource[4], theseminal paper by Nöth et al. in 1985 [3] marked the beginning of interest by the organic ch- istry community in the application of this reaction in organic synthesis [5].
