Abstract

Dichlorophenylphosphine reacts with indenyllithium in tetrahydrofuran followed by sulfur to yield di(1H-inden-3-yl)phenylphosphine sulfide (2). The same reaction sequence in toluene yields di(1H-inden-1-yl)phenylphosphine sulfide (3) as a mixture of (±) and two meso isomers. The structures of (2) and (±)-(3) were determined [(2): C24H19PS, Mr 370·42, monoclinic, P21/n, a 14·329(4), b 7·0936(10), c 19·405(5) Å, β 99·18(2)°, Z 4, R 0·060 for 2422 observed reflections; (3): C24H19PS, Mr 370·42, monoclinic, P21/n, a 9·521(5), b 16·223(8), c 12·930(6) Å, β 107·41(3)°, Z 4, R 0·105 for 923 reflections].
