Remarkable organophosphorus cage compounds from the reaction of cobaltocene and the triphosphole P3C2But2CH(SiMe3) 2: crystal and molecular structures of [Co(η5-C5H5)(η4-C 4H4CHCHP6C4But 4)] and P6C4But4CH(SiMe3)

The novel cage compounds [Co(η5-C5H5)(η4-C 4H4CHCHP6C4But 4)] and P6C4But4CH(SiMe3) are formed from the reaction between cobaltocene and the triphosphole P3C2But2CH(SiMe3)

Room temperature electrocyclisation of the 1,2,4-triphosphole P3C2But2CH(SiMe3)2 affords the new 1,3,5-triphosphabicyclo[2.1.0]pent-2-ene which undergoes a very rapid [1,3]-phosphorus migration which can be stopped by coordination of [W(CO)5]; the two isomeric phosphorus compounds react differently with [PtCl2(PEt3)]2, the latter via an insertion of the metal into the P–P bond and a chlorine migration reaction to afford trans-[PtCl(PEt3)P2C2- But2PClCH(SiMe3)2], the molecular structure of which has been determined by a single crystal X-ray diffraction study.

Protonation of the lithium triphospha-cyclopentenyl salt Li (P3C2But2RR′) (R=(Me3Si)2CH-, R′=Bun) with HCl affords the new 2,3-dihydro-1H-[1,2,4] triphosphole P3C2But2(H) (Bun)CH(SiMe3)2 which has been structurally characterised as its [W(CO)5] complex.

The synthesis of the first 1,2,4-triphosphacyclopentadiene, 1 has been reported1 and its coordination chemistry widely studied. In this work, we present the synthesis of two new cages, 2 and 3, formed from the coupling of two molecules of 1 with looses of CH(SiMe3)3. Compound 2 has an open structure with two double bonds and a CHSiMe3 bridging twophosphorus atoms. The structure of compound 3 is more
