Unlike the parent pentagonal-pyramidal closo-2,4-C2B5H7, both 3-Cl-closo-2,4-C2B5H6 and 5-Cl-closo-2,4-C2B5H6 readily react with (CH3)3L (L = N, P) to form 1:1 adducts. Removal of Cl- from these two adducts, using BCl3, produces the unique [3-(CH3)3L-closo-2,4-C2B5H 6]+ and [5-(CH3)3L-closo-2,4-C2B5H 6]+ cations, respectively. The reaction of (CH3)3N with 1-Cl-closo-2,4-C2B5H6 proceeds with more difficulty than with the other two B-Cl isomers, but once formed, the 1:1 adduct combines with BCl3 to give the rearrangement product [3-(CH3)3N-closo-2,4-C2B5H 6]+[BCl4]-.
