Retention of Pt→B Bonding in Oxidative Addition Reactions of the Platinaboratrane [Pt(PPh3){B(mt)3}](Pt→B)10 (mt = Methimazolyl)

The platinaboratrane [Pt(PPh 3 ){B(mt) 3 }] (Pt→B) 10 (mt = methimazolyl) is prone to oxidative addition reactions with a range of substrates (Cl 2, Br 2, I 2, HCl, CH 3 I) without disrupting the platinum−boron dative bond, as illustrated by the first structurally characterized platinaboratranes [PtH(PPh 3 ){B(mt) 3 }]Cl (Pt→B) 8 and [PtI 2 {B(mt) 3 }] (Pt→B) 8 .
