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.

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
