The ethylene-bridged bisphosphine, [2-(dimethylphosphino)ethyllbis(trifluoromethyl)phosphine, [(CH~),PCH,CH,P(CF3)2], was synthesised in four steps from the unsymmetrical bisphosphine (CH0,PCH2CH2PH v using a new trifluoromethylation procedure employing CF3Br and hexaethylphosphorus triamide.

1,1-Bis(dimethylamino)-2,2,2-trifluoroethane is an excellent synthetic building-block replacement for trifluoroacetaldehyde in condensation reactions with ketones using 36% aqueous HCI catalysis. Moderate to good yields (43-68%) of trifluoromethyl carbinols are obtained with symmetric and unsymmetri
