Abstract: 1452196 Phosphines and complexes thereof with rhodium; hydrogenation of substituted acrylic acids RHONE-POULENC SA 20 May 1974 [21 May 1973] 22343/74 Headings C2P and C2C The invention comprises a stereoisomer of a diphosphine of Formula I where the phosphinomethyl groups are in the transposition relative to one another and R 1 , R 2 , R<SP>1</SP> 1  and R<SP>1</SP> 2  are C 1-8  alkyl, C 5  or C 6  cycloalkyl or aryl consisting of one or more benzene rings which are bonded to one another by a valency bond or which form with one another an ortho- or pericondensed system, the said aryl being optionally substituted by C 1-4  alkyl; and a rhodium complex in which the rhodium is bound to halogen and a diphosphine of Formula I. The diphosphines of Formula I may be prepared by reacting a phosphide of formula R 1 R 2 M where M is alkali metal, alone or with a phosphide of formula R<SP>1</SP> 1 R<SP>1</SP> 2 M, with a sulphonic acid diester of a stereoisomer of trans-bis-(1,2- hydroxymethyl) cyclobutane. The rhodium complexes may optionally also contain CO groups and may be prepared by (a) reacting a complex of rhodium and a mono- or diolefine with a phosphine of Formula I or (b) reacting an excess of a disphosphine of Formula I with RhCl 3 .3H 2 O. Complexes containing Cl may be converted to complexes containing I or Br by reaction with LiBr or LiI and may be converted to complexes containing CO by reaction with carbon monoxide. The (+) and (-) stereoisomers of trans-bis- (1,2-hydroxymethyl) cyclobutane are prepared by reducing (-) or (+) -transcyclobutanedicarboxylic acid, respectively, with lithium aluminium hydride. The asymmetric hydrogenation of a substituted acrylic acid or ester thereof is carried out by hydrogenating a mixture of the acid or ester and a rhodium complex of the invention. Preferably the acid or ester is a compound whose formula is derived from that of acrylic acid or an ester thereof by replacing one hydrogen atom carried by the ethylenic carbon atoms by a primary or secondary amino group, which may be acylated, and optionally replacing one other hydrogen atom by alkyl, cycloalkyl, optionally substituted aryl or a heterocyclic group.

Abstract: 644,398. Packing. ROSE BROS. (GAINSBOROUGH), Ltd. Aug. 16, 1947, No. 22834. [Class 94(i)] The open end of a partially filled bag is seized so as to nip portions of opposing sides of the bag together, and then the bag is closed by twisting its open end above the level at which the bag is nipped so as to form a twisted neck 17.
