Abstract

<jats:title>Abstract</jats:title><jats:p> The phase-transfer-catalytically in situ generated dihalocarbenes CCl<jats:sub>2</jats:sub> and CBr<jats:sub>2</jats:sub> are inserted into a β-C-H bond of the five-and six-membered phosphamanganacycloalkanes (OC)<jats:sub>4</jats:sub>[xxx] (1a, b) [n = 1(a), 2(b)] to give the functionalized metallacycles (OC)<jats:sub>4</jats:sub>[xxx](2a, a′, b, b′) [X = Cl: n = 1(a), 2(b); X = Br: n = 1(a′), 2(b′)]. 2b crystallizes in the orthorhombic space group Pbca with Z = 8 and has a distorted chair conformation with equatorial position of the CHCl<jats:sub>2</jats:sub> group. The envelope conformation of 2a in solution was elucidated by means of <jats:sup>1</jats:sup>H and <jats:sup>13</jats:sup>C{<jats:sup>1</jats:sup>H} NMR spectroscopic investigations.</jats:p>
