A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.

A crosslinking agent comprising an asymmetry organic peroxide having at least one structure unit of (substituted)benzoylcarbonyloxy group represented by the following formula (1) in the molecule thereof.
Environmentally friendly crosslinking agents and crosslinked silicone rubber moldings are provided thereby.
Specifically, useful crosslinking agents and crosslinking processes for silicone rubber are provided.
Compounds of the formula ##STR1## WHEREIN A is a linking group, X is an O--CO-- or --SO.sub.2 -- group and n is at least 2, are prepared from the corresponding N',N'-disubstituted hydrazides by quaternization and treatment with alkali or reaction with an alkylene epoxide or from the corresponding compound wherein n = 1 and A is a polymerizable group by polymerization. The compounds are unstable to heat and may be used as cross-linking agents for polymers or as chain-extending agents, bonding agents or adhesives.

Routine screening of compounds for inhibition of ADP-inducedplateletaggregation in vitro revealed that 1,1'-hexamethylenebis[3-cyclohexyl-3-[(cyclohexylimino) (4-morpholinyl) methyl]urea] (1) was active and represented the first example of a bis(acylguanidine) with possible antithrombotic activity. In order to develop a structure-activity relationship for this class of compounds, we synthesized a
The present invention provides compounds of formula M-L-M′ (where M and M′ are each independently a monomeric moiety of Formula (I) and L is a linker). The dimeric compounds have been found to be effective in promoting apoptosis in rapidly dividing cells.
