The regioselectivity of the palladium catalyzed allylic alkylation was studied systematically using bidentate ligands based on a xanthene backbone, bearing different donor atoms. The nature of the ligand donor atoms has a pronounced influence on the

New wide bite angle amine, arsine and mixed phosphineamine and phosphinearsine ligands based on xanthene backbones were synthesized. The co-ordination chemistry and the catalytic performance of these ligands were compared to those of the parent phosp

By a sol-gel process a rhodium complex containing a diphosphane with a large natural P-Rh-P bite angle is covalently anchored in a silica matrix (see picture). The immobilized catalyst is a very selective hydroformylation catalyst that is completely

Reaction of naphthalic anhydride (naphthalene-1,8-dicarboxylic anhydride) (1) or of 1,8-bis(hydroxymethyl)naphthalene (3) with LiAlH4 in refluxing THF yields the benzonorcaradiene derivatives 2 in yields of up to 50%. It is proposed that in the forma

Recent advances in rhodium catalyzed hydroformylation using xanthene-based ligands will be reviewed. The calculated natural bite angles of the ligands discussed are in the range 100–123°. While the general trend is clear—higher 1: b ratios at wi
