A novel preparation of 1-chloro-3-methyl-3-phospholenium chlorides was developed by reacting 1-substituted-3-methyl-3-phospholene 1-oxides with oxalyl chloride. The obtained cyclic chlorophosphonium salts were reacted with LiBH4to afford the corresponding 1-substituted-3-methyl-3-phospholene boranes. The latter protocol involves a silane-free deoxygenation, and borane complex formation. In one instance, a 2-phospholene borane and the corresponding P-oxide were synthesized via rearrangement of the double bond in the cyclic chlorophosphonium salt. This double bond migration was investigated by quantum chemical calculations.

New platinum complexes of the type cis-Pt(L)2Cl2 have been synthesized from five-and six-membered cyclic phosphines, which were prepared after deoxygenating a series of phosphine oxides (3-phospholene oxides, phospholane oxides, a 1,

Ru- and Mo-based catalysts can be used in ring closing metathesis (RCM) reactions to synthesise cyclic phosphines protected as their borane complexes. The compatibility of the Schrock Mo-catalyst and the N-heterocyclic carbene Ru-catalysts with this class of substrates is particularly noteworthy as asymmetric RCM (ARCM) is now emerging as a new tool for the preparation of homochiral phosphines. One of the key results is that the Mo-catalyst allows the ring closure of the unprotected diallyphenylphosphine with 95% conversion.

Grubbs' catalyst [Cl2Ru{P(C2H11)2}2 = CHPh] can be used to synthesize borane complexes of cyclic phosphanes by ring-closing metathesis reactions. This strategy has been applied, for example, to the preparation of a borane-protected bisphosphanes [Eq. (1)].

Dihydro-1H-phosphole-boranes 5 and 10 were prepared from phosphine oxides 1 and 9 respectively. Reaction of borane 5 with dichlorocarbene gave dihydrophosphole-dichloromethylborane 6 and tetrahydro derivative 7a as the main products, and dichlorocycloprop
