## Abstract Monoketones react with hydrogen sulfide in the presence of basic catalysts to give geminal dithiols or thioketones. β‐Diketones are converted into monothiodiketones. α‐Diketones can be selectively reduced by hydrogen sulfide in the cold in the presence of secondary or tertiary amines to

Copolymers of aliphatic aldehydes containing a trimethylsilyl group were prepared a t -78°C in toluene using diethylaluminum diphenylamide as an initiator. The copolymer depolymerized into monomeric aldehydes on exposure t o soft X-rays. When the copolymer was used as a soft X-ray resist, almost com
## Abstract A series of diphosphines of the novel Walphos ligand family all based on a phenylferrocenylethyl backbone were synthesised in a four‐step sequence. In the rhodium‐ or ruthenium‐catalysed asymmetric hydrogenation of olefins and ketones enantioselectivities of up to 95% and 97%, respectiv
