Background: There has been significant reduction in inpatient beds for people with intellectual disability and/or autism (PwID/A) in the UK in the last decade following high profile national scandals in specialist psychiatric hospitals. To reduce inappropriate admissions a new strategy (Blue-Light, an emergency multi-disciplinary meeting to prevent admission to hospital) was introduced. However, there is no research on the influence of Blue-Light on crisis management for PwID/A.

Background: People with severe mental illness are often excluded from trials related to Eye Movement Desensitization and Reprocessing (EMDR) therapy. Principal concerns are that they may not tolerate treatment, might risk relapse or that psychotic symptoms may worsen. There is however building evidence of a traumatogenic etiology of psychotic disorder that may benefit therapeutically from EMDR.

Cyclotriphosphazenes have been functionalized with various oxo-groups at one of the ring phosphorus atoms. Starting from geminal dichlorides (A) which are equipped with amino groups at the other two phosphorus atoms {(Z'(2)P)(2)N(3)PCl(2) (Z' = NHCy) and (Z''P)(2)N(3)PCl(2) (Z'' = {EtN(C(3)H(6))NEt}), respectively}, phosphate (B), pyrophosphate (C), phosphamide (D), and phosphite (E) derivatives have been prepared. The zwitterionic phosphate (Z'(2)P)(2)N(3)H(2)PO(2) B is obtained via the 4-dimethylamino pyridine (dmap)-catalyzed hydrolysis of A in a biphasic mixture of aqueous KOH and tetrahydrofuran (thf).

Zwitterionic ligands are readily prepared from phosphazenes (RNH)6P3N3 by successive alkylation of ring nitrogen sites and deprotonation of exocyclic NH sites.

The cyclotriphosphazene P(3)N(3)Cl(6) reacts with six equivalents of DMAP (4-(dimethylamino)pyridine) in superheated chloroform to form crystals of composition [P(3)N(3)(DMAP)(6)]Cl(6).19CHCl(3) comprising [P(3)N(3)(DMAP)(6)](6+) ions, which host five chloride ions in basket-type cavities on either side of the ring and at equatorial positions via tetradentate ortho-H-donor arrangements.
